International conference proceedings, English - Solving multi-armed bandit problems using a chaotic microresonator comb

APL Photonics, AIP Publishing, 9, 3, 01 Mar. 2024, Peer-reviwed, The Multi-Armed Bandit (MAB) problem, foundational to reinforcement learning-based decision-making, addresses the challenge of maximizing rewards amid multiple uncertain choices. While algorithmic solutions are effective, their computational efficiency diminishes with increasing problem complexity. Photonic accelerators, leveraging temporal and spatial-temporal chaos, have emerged as promising alternatives. However, despite these advancements, current approaches either compromise computation speed or amplify system complexity. In this paper, we introduce a chaotic microresonator frequency comb (chaotic comb) to tackle the MAB problem, where each comb mode is assigned to a slot machine. Through a proof-of-concept experiment, we employ 44 comb modes to address an MAB with 44 slot machines, demonstrating performance competitive with both conventional software algorithms and other photonic methods. Furthermore, the scalability of decision making is explored with up to 512 slot machines using experimentally obtained temporal chaos in different time slots. Power-law scalability is achieved with an exponent of 0.96, outperforming conventional software-based algorithms. Moreover, we find that a numerically calculated chaotic comb accurately reproduces experimental results, paving the way for discussions on strategies to increase the number of slot machines.

Last, Applied Physics Express, IOP Publishing, 17, 2, 022001-022001, 14 Feb. 2024, Peer-reviwed, True, Abstract
We demonstrated an ultrafast time-resolved measurement method operating at the single-photon level and employing a two-color comb-based asynchronous optical sampling (ASOPS) setup. We harnessed the two-color ASOPS photon counting approach to achieve long-term averaging of the ultralow intensity signal with a synchronized optical trigger signal, which minimizes residual timing jitter between the two combs. A pulse-width limited picosecond cross-correlation signal was successfully obtained with a power level of <1 photon/pulse. This approach enables the thorough study of ultrafast time-resolved detection of entangled photon pairs, quantum mechanical correlations in the time-frequency domain and finds wide use in optical quantum technology.

Last, Optics Express, Optica Publishing Group, 31, 7, 11695-11695, 23 Mar. 2023, Peer-reviwed, True, By combining dual-comb spectroscopy and optical vortices, which have the orbital angular momentum (OAM) of light, we propose a novel measurement concept, “dual-vortex-comb spectroscopy (DVCS).” We extend the dual-comb spectroscopy to angle dimensions by utilizing the characteristic helical phase structure of optical vortices. We demonstrate a proof-of-principle experiment on DVCS that realizes in-plane azimuth-angle measurements with an accuracy of ∼0.1 mrad after cyclic error correction, whose origin is verified by a simulation. We also demonstrate that the measurable angle range is tailored by the topological number of the optical vortices. This is the first demonstration of dimensional conversion between the in-plane angle and dual-comb interferometric phase. This successful result can expand the applicability of optical frequency comb metrology to new dimensions.

A coherently synthesized 1550/1560 nm two-color EO comb is generated by modulating two continuous-wave lasers with common EO modulators and phase-locking their beat note. Compared with a single-color EO comb, the phase noise of comb modes that accumulated from the RF synthesizer is effectively suppressed in our coherently synthesized two-color EO comb. Besides, a broader spectrum is demonstrated in a coherently synthesized 1535/1560 nm two-color EO comb, with a 60-nm total spectrum span. The coherently synthesized two-color EO combs are expected to be applied in coherent communication, spectroscopy, absolute distance measurement, etc.
Scientific journal, English - Low phase noise THz generation from a fiber-referenced Kerr microresonator soliton comb

Communications Physics, Springer Science and Business Media LLC, 5, 1, 02 Dec. 2022, Peer-reviwed, Abstract
THz oscillators generated via frequency-multiplication of microwaves are facing difficulty in achieving low phase noise. Photonics-based techniques, in which optical two tones are translated to a THz wave through opto-electronic conversion, are promising if the relative phase noise between the two tones is well suppressed. Here, a THz (≈560 GHz) wave with a low phase noise is provided by a frequency-stabilized, dissipative Kerr microresonator soliton comb. The repetition frequency of the comb is stabilized to a long fiber in a two-wavelength delayed self-heterodyne interferometer, significantly reducing the phase noise of the THz wave. A measurement technique to characterize the phase noise of the THz wave beyond the limit of a frequency-multiplied microwave is also demonstrated, showing the superior phase noise of the THz wave to any other photonic THz oscillators (>300 GHz).

Last, Applied Physics Letters, AIP Publishing, 121, 11, 211104-1-211104-6, 21 Nov. 2022, Peer-reviwed, We demonstrate balanced-detection dual-comb spectroscopy using two free-running mechanical sharing dual-comb fiber lasers assisted by an all-computational digital phase correction algorithm. The mutual coherence between the combs allows us perform mode-resolved spectroscopy of gaseous hydrogen cyanide by digitally compensating residual timing and offset frequency fluctuations of the dual-comb signal. Setting the repetition rate difference between the combs to 500 Hz (1.5 kHz) yields more than 2000 resolved radio frequency comb lines after phase correction in a 3-dB bandwidth centered at 1560 nm of wavelength. Through coadding the corrected interferograms, we obtain a single time-domain trace with a signal-to-noise ratio (SNR) of 6378 (13 960) and 12.64 (13.77) bits of dynamic range in 1 s of averaging. The spectral SNR of the coadded trace reaches 529 (585), corresponding to a figure of merit of SNR of 1.3 × 106 (1.4 × 106). The measured absorption spectrum of hydrogen cyanide agrees well with the HITRAN database.

Last, Opt. Continuum, Optica (OSA), 1, 11, 2374-2388, 17 Nov. 2022, Peer-reviwed, Using spectral interference from a highly chirped and high-repetition-rate optical frequency comb, a technique for dead-zone free one-shot three-dimensional (3D) imaging was developed. We generated continuously emitted pulse train (dead-zone-free pulse) using a highly chirped pulse from a 750-MHz repetition mode-locked Yb fiber comb. The measurement performances of the system were evaluated using an optical spectrum analyzer, and a longitudinal delay length resolution of 31 µm was obtained at arbitrary position for more than 400 mm range. Using an imaging spectrometer capable of multipoint spectroscopy, a delay length resolution of 81 µm was demonstrated. Finally, for a proof-of-concept measurement of 3D imaging, line profiles of three mirrors located in the middle of 200-mm-distance, corresponding to pulse-to-pulse interval, were measured without any scanning with an uncertainty of 0.7 mm. The uncertainty could be further improved by optical alignment and analysis to the level of 10 ∼ 100 µm at arbitrary position over the range not limited to pulse-to-pulse interval.

Last, Optics Express, Optica (OSA), 30, 16, 28427-28437, 01 Aug. 2022, Peer-reviwed, We present quasi-real-time dual-comb spectroscopy (DCS) using two Yb:fiber combs with ∼750 MHz repetition rates. A computational coherent averaging technique is employed to correct timing and phase fluctuations of the measured dual-comb interferogram (IGM). Quasi-real-time phase correction of 1-ms long acquisitions occurs every 1.5 seconds and is assisted by coarse radio frequency (RF) phase-locking of an isolated RF comb mode. After resampling and global offset phase correction, the RF comb linewidth is reduced from 200 kHz to ∼1 kHz, while the line-to-floor ratio increases 13 dB in power in 1 ms. Using simultaneous offset frequency correction in opposite phases, we correct the aliased RF spectrum spanning three Nyquist zones, which yields an optical coverage of ∼180 GHz around 1.035 µm probed on a sub-microsecond timescale. The absorption profile of gaseous acetylene is observed to validate the presented technique.

Optics Letters, Optica Publishing Group, 47, 2, 281-281, 06 Jan. 2022, Peer-reviwed, True, We report the thermal control of a dissipative Kerr microresonator soliton comb via an optical sideband generated from an electro-optic modulator. Same as the previous reports using an independent auxiliary laser, our sideband-based (S-B) auxiliary light also enables access to a stable soliton comb and reduces the phase noise of the soliton comb, greatly simplifying the set-up with an auxiliary laser. More importantly, because of the intrinsically high frequency/phase correlation between the pump and S-B auxiliary light, the detuning between the pump and resonance frequency is automatically almost fixed, which allows an 18 times larger “effective" soliton existence range than the conventional method using an independent auxiliary laser, as well as a scanning of the soliton comb of more than 10 GHz without using microheaters.

Last, Optics Express, Optica (OSA), 29, 26, 43778-43792, 20 Dec. 2021, Peer-reviwed, Using spectral interference from a chirped optical frequency comb, we developed a one-shot three-dimensional (3D) imaging method. We formed a two-dimensional spectrometer using fiber bundles made up of single-mode and multi-mode fibers to detect the spectral interference fringe images. The proposed method demonstrated one-shot 3D imaging of reflective targets with sub-µm level depth uncertainty and a wide dynamic range of 6 digits. Furthermore, by developing a method to remove the speckle noise caused by multi-mode fibers, we succeeded in capturing 3D profiles with sub-µm uncertainty in a one-shot with 299 times higher efficiency than single-mode fibers using a large numerical aperture.

Last, Optics Express, The Optical Society, 29, 4, 5018-5032, 15 Feb. 2021, Peer-reviwed, Dual-comb microscopy (DCM), an interesting imaging modality based on the optical-frequency-comb (OFC) mode and image pixel one-to-one correspondence, benefits from scan-less full-field imaging and simultaneous confocal amplitude and phase imaging. However, the two fully frequency-stabilized OFC sources requirement hampers DCM practicality due to the complexity and costs. Here, a bidirectional single-cavity dual-comb fiber laser (SCDCFL) is adopted as a DCM low-complexity OFC source. Although the residual timing jitter in the SCDCFL blurs the image of a static object acquired by DCM, computational image correction significantly suppresses the image blur. Nanometer-order step surface profilometry with a 14.0 nm uncertainty highlights the computationally image-corrected DCM effectiveness. We further discuss a possibility to expand the computational image correction to a dynamic object and demonstrate its preliminary experiment. The proposed method enhances the DCM generality and practicality due to low-complexity OFC source.

Seventh European Workshop on Optical Fibre Sensors, Proceedings of SPIE, SPIE, 11199, 111991D-1-111991D-4, 28 Aug. 2019, Peer-reviwed, Refractive index measurement is important for evaluation of liquid materials, optical components, and bio sensing. One promising approach for such measurement is use of optical fiber sensors such as surface plasmonic resonance or multimode interference (MMI), which measure the change of optical spectrum resulting from the refractive index change. However, the precision of refractive index measurement is limited by the performance of optical spectrum analyzer. If such the refractive index measurement can be performed in radio frequency (RF) region in place of optical region, the measurement precision will be further improved by the frequency-standard-based RF measurement. To this end, we focus on the disturbance-To-RF conversion in a fiber optical frequency comb (OFC) cavity. Since frequency spacing frep of OFC depends on an optical cavity length nL, frep sensitively reflects the external disturbance interacted with nL. Although we previously demonstrated the precise strain measurement based on the frep measurement, the measurable physical quantity is limited to strain or temperature, which directly interacts with the fiber cavity itself. If a functional fiber sensor can be installed into the fiber OFC cavity, the measurable physical quantity will be largely expanded. In this paper, we introduce a MMI fiber sensor into a ring-Type fiber OFC cavity for refractive index measurement. We confirmed the refractive-indexdependent shift of optical spectrum event though the MMI fiber sensor is included in the cavity. Such the spectral shift was converted into refractive-index-dependent shift of frep via the wavelength dispersion of the cavity fiber.

JAPANESE JOURNAL OF APPLIED PHYSICS, IOP PUBLISHING LTD, 58, 6, 060912-1-060912-5, Jun. 2019, Peer-reviwed, A mode-locked fiber comb equipped with a multimode interference fiber sensor functions as a high-precision refractive-index (RI) sensor benefitting from precise RF measurement. However, its dynamic range and repeatability are hampered by the inherent characteristics of nonlinear-polarization-rotation mode-locking oscillation. In this article, we introduce saturable-absorber-mirror mode-locking for RI sensing with a wide dynamic range and high repeatability. While the RI dynamic range was expanded to 41.4 dB due to high robustness against cavity disturbance, the self-starting capability without the need for polarization control improves the RI sensing repeatability to 1.10 x 10(-8) for each mode-locking activation. The improved dynamic range and repeatability will be useful for enhancing the performance of RI sensing. (C) 2019 The Japan Society of Applied Physics

OPTICAL FIBERS AND SENSORS FOR MEDICAL DIAGNOSTICS AND TREATMENT APPLICATIONS XIX, SPIE-INT SOC OPTICAL ENGINEERING, 10872, 2019, Peer-reviwed, Optical frequency combs (OFCs) have attracted attention as optical frequency rulers due to their tooth-like discrete spectra together with their inherent mode-locking nature and phase-locking control to a frequency standard. Based on this concept, their applications until now have been demonstrated in the fields of optical frequency metrology. However, if the utility of OFCs can be further expanded beyond their application by exploiting new aspects of OFCs, this will lead to new developments in optical metrology and instrumentation. Previously, we reported a fiber sensing application of OFCs based on a coherent link between the optical and radio frequencies, enabling high-precision refractive index (RI) measurement based on frequency measurement in radio-frequency (RF) region. Our technique encoded an RI change of a liquid sample into a repetition frequency of OFC by a combination of an intracavity multi-mode-interference fiber sensor and wavelength dispersion of a cavity fiber. Then, the change in refractive index was read out with an RI resolution of 4.88 x 10(-6) RIU and an RI accuracy of 5.35 x 10(-5) RIU by measuring the repetition frequency in RF region based on a frequency standard. However, the temperature instability of a sample limits the performance because a refractive index is a function of temperature. In this paper, we demonstrate simultaneous measurement of concentration and temperature in a sample by measuring RI-dependent repetition frequency shift and optical spectrum shift.

Optica, OSA - The Optical Society, 5, 5, 634-643, 20 May 2018, Peer-reviwed, Confocal laser microscopy (CLM) is a powerful tool in life science research and industrial inspection because it offers two-dimensional optical sectioning or three-dimensional imaging capability with micrometer depth selectivity. Furthermore, scan-less imaging modality enables rapid image acquisition and high robustness against surrounding external disturbances in CLM. However, the objects to be measured must be reflective, absorptive, scattering, or fluorescent because the image contrast is given by the optical intensity. If a new image contrast can be provided by the optical phase, scan-less CLM can be further applied for transparent non-fluorescent objects or reflective objects with nanometer unevenness by providing information on refractive index, optical thickness, or geometrical shape. Here, we report scan-less confocal dual-comb microscopy offering a phase image in addition to an amplitude image with depth selectivity by using an optical frequency comb as an optical carrier of amplitude and phase with discrete ultra-multichannels. Our technique encodes confocal amplitude and phase images of a sample onto a series of discrete modes in the optical frequency comb with well-defined amplitude and phase to establish a one-to-one correspondence between image pixels and comb modes. The technique then decodes these images from comb modes with amplitude and phase. We demonstrate confocal phase imaging with milliradian phase resolution under micrometer depth selectivity on the millisecond timescale. As a proof of concept, we demonstrate the quantitative phase imaging of standing culture fixed cells and the surface topography of nanometer-scale step structures. Our technique for confocal phase imaging will find applications in three-dimensional visualization of stacked living cells in culture and nanometer surface topography of semiconductor objects.

Optics Express, OSA - The Optical Society, 26, 8, 9484-9491, 16 Apr. 2018, Peer-reviwed, We propose an optical frequency comb (OFC)-based strain sensing method, namely OFC sensing cavity, which is capable of radio-frequency (RF)-based strain measurement. We developed a null-method-based strain sensing system with a comb-spacing-stabilized OFC generator. We realized strain measurement from 1.83 µε to 1800 µε with a sensing fiber length of 20 mm. The measurable strain frequency range of the developed strain sensing system was from 0 to 310 Hz. Owing to the use of RF-based strain measurement, our approach would be a useful and powerful tool for sensing of strain or other physical quantities, and the concept of the OFC sensing cavity is a new aspect of OFC technology.

Last, Optics Express, OSA - The Optical Society, 26, 7, 8957-8967, 02 Apr. 2018, Peer-reviwed, We demonstrated Doppler-free two-photon absorption dual-comb spectroscopy of 5S1/2-5D5/2 and 5D3/2 transitions of Rb. We employed simple pulseshaping of the dual-comb source and eliminated Doppler-broadening backgrounds, which cause fitting errors of the Doppler-free signals. Moreover, to improve sensitivity, we investigated the coherence in dual-comb fluorescence signals and the coherent averaging method was applied to fluorescence dual-comb detection for the first time. The detection sensitivity was significantly improved by coherent averaging to reduce the noise floor. Observed Doppler-free spectra was fitted to Voigt profiles and we performed absolute frequency determination with a precision of about 100 kHz.

Last, Optics Express, OSA - The Optical Society, 26, 4, 4656-4664, 19 Feb. 2018, Peer-reviwed, We developed a mode-filtering technique based on the all-fiber-based external cavity for a fiber-based optical frequency comb for high repetition rate (frep) frequency comb, and the carrier envelope offset frequency (fceo) can be detected and stabilized and is robust to environmental fluctuations. To achieve multiplication of the frep with a high multiplication factor using the fiber ring cavity, a long fiber was developed to mitigate the physical limitation inhibiting the shortening of the cavity length. In this study, the length of the fiber cavity was set to 6.7 m (free spectral range = 44.7 MHz) as the fiber-based comb length was 6.1 m. We were able to demonstrate a multiplication factor of 11, i.e., frep increased from 48.7 MHz to 536.0 MHz with a side mode suppression ratio of about 25 dB using the double-pass configuration.

Progress in Biomedical Optics and Imaging - Proceedings of SPIE, SPIE, 10494, 2018, Peer-reviwed, Compressional wave detection is useful means for health monitoring of building, detection of abnormal vibration of moving objects, defect evaluation, and biomedical imaging such as echography and photoacoustic imaging. The frequency of the compressional wave is varied from quasi-static to a few tens of megahertz depending on applications. Since the dynamic range of general compressional wave detectors is limited, we need to choose a proper compressional wave detector depending on applications. For the compressional wave detection with wide dynamic range, two or more detectors with different detection ranges is required. However, these detectors with different detection ranges generally has different accuracy and precision, disabling the seamless detection over these detection ranges. In this study, we proposed a compressional wave detector employing optical frequency comb (OFC). The compressional wave was sensed with a part of an OFC cavity, being encoded into OFC. The spectrally encoded OFC was converted to radio-frequency by the frequency link nature of OFC. The compressional wave-encoded radio-frequency can therefore be directly measured with a high-speed photodetector. To enhance the dynamic range of the compressional wave detection, we developed a cavityfeedback-based system and a phase-sensitive detection system, both of which the accuracy and precision are coherently linked to these of the OFC. We provided a proof-of-principle demonstration of the detection of compressional wave from quasi-static to ultrasound wave by using the OFC-based compressional wave sensor. Our proposed approach will serve as a unique and powerful tool for detecting compressional wave versatile applications in the future.

OPTICAL FIBERS AND SENSORS FOR MEDICAL DIAGNOSTICS AND TREATMENT APPLICATIONS XVIII, SPIE-INT SOC OPTICAL ENGINEERING, 10488, JW2A.146, 2018, Peer-reviwed, Refractive index measurement is important for evaluation of liquid materials, optical components, and bio sensing. One promising approach for such measurement is use of optical fiber sensors such as surface plasmonic resonance or multi-mode interference (MMI), which measure the change of optical spectrum resulting from the refractive index change. However, the precision of refractive index measurement is limited by the performance of optical spectrum analyzer. If such the refractive index measurement can be performed in radio frequency (RF) region in place of optical region, the measurement precision will be further improved by the frequency-standard-based RF measurement.To this end, we focus on the disturbance-to-RF conversion in a fiber optical frequency comb (OFC) cavity. Since frequency spacing f(rep) of OFC depends on an optical cavity length nL, f(rep) sensitively reflects the external disturbance interacted with nL. Although we previously demonstrated the precise strain measurement based on the f(rep) measurement, the measurable physical quantity is limited to strain or temperature, which directly interacts with the fiber cavity itself. If a functional fiber sensor can be installed into the fiber OFC cavity, the measurable physical quantity will be largely expanded. In this paper, we introduce a MMI fiber sensor into a ring-type fiber OFC cavity for refractive index measurement. We confirmed the refractive-index-dependent f(rep) shift.

We compared the dual-comb signals in three dual-comb setups consisting of combinations of two combs with and without mode-filtering, and investigated how the repetition rate influences the signal-to-noise ratio (SNR) of dual-comb measurements. The dual-comb setups using high-repetition-rate combs enabled the absorption lines of HCN gas to be measured with a high SNR in a short averaging time, and real-time spectral data acquisition was realized using a low-sensitivity and low-resolution RF spectrum analyzer.

OPTICS EXPRESS, OPTICAL SOC AMER, 25, 18, 21947-21957, Sep. 2017, Peer-reviwed, We have developed a hyperspectral imaging scheme that involves a combination of dual-comb spectroscopy and Hadamard-transform-based single-pixel imaging. The scheme enables us to obtain 12,000 hyperspectral images of amplitude and phase at a spatial resolution of 46 mu m without mechanical scanning. The spectral resolution given by the data point interval in the frequency domain is 20 MHz and the comb mode interval is 100 MHz over a spectral range of 1.2 THz centered at 191.5 THz. As an initial demonstration of our scheme, we obtained spectroscopic images of a standard test chart through an etalon plate. The thickness of an absorptive chromium-coated layer on a float-glass substrate was determined to be 70 nm from the hyperspectral phase images in the near-infrared wavelength region.

Simultaneous times of flight from multiple positions to a target encoded in a chirped optical frequency comb can be obtained from spectral interferometry. We experimentally demonstrate a one-shot imaging profile measurement of a known step height of 480 mu m with mu m-level accuracy. We further demonstrate the extension of the dynamic range by measuring in one shot a large step height of 3m while maintaining high accuracy using the accurate pulse-to-pulse separation of the optical frequency comb. The proposed method with its large dynamic range and measurement versatility can be applied to a broad range of applications, including microscopic structures, objects with large size or aspect ratio, and ultrafast time-resolved imaging. This study provides a powerful and versatile tool for 3D measurement, where various ranges of measurement performances can be tailored to demand.

Journal of Infrared, Millimeter, and Terahertz Waves, Springer New York LLC, 37, 9, 903-915, 01 Sep. 2016, Peer-reviwed, A terahertz (THz) frequency synthesizer based on photomixing of two near-infrared lasers with a sub-THz to THz frequency offset is a powerful tool for spectroscopy of polar gas molecules due to its broad spectral coverage
however, its frequency accuracy and resolution are relatively low. To tune the output frequency continuously and widely while maintaining its traceability to a frequency standard, we developed a photomixing THz synthesizer phase-locked to dual optical frequency combs (OFCs). While the phase-locking to dual OFCs ensured continuous tuning within a spectral range of 120 GHz, in addition to the traceability to the frequency standard, use of a broadband uni-traveling carrier photodiode for photomixing enabled the generation of CW-THz radiation within a frequency range from 0.2 to 1.5 THz. We demonstrated THz frequency-domain spectroscopy of gas-phase acetonitrile CH3CN and its isotope CH3 13CN in the frequency range of 0.600–0.720 THz using this THz synthesizer. Their rotational transitions were assigned with a frequency accuracy of 8.42 × 10−8 and a frequency resolution of 520 kHz. Furthermore, the concentration of the CH3CN gas at 20 Pa was determined to be (5.41 ± 0.05) × 1014 molecules/cm3 by curve fitting analysis of the measured absorbance spectrum, and the mixture ratio of the mixed CH3CN/CH3 13CN gas was determined to be 1:2.26 with a gas concentration of 1014–1015 molecules/cm3. The developed THz synthesizer is highly promising for high-precision THz-FDS of low-pressure molecular gases and will enable the qualitative and quantitative analyses of multiple gases.

Proceedings of JSPE Semestrial Meeting, The Japan Society for Precision Engineering, 2016, 0, 59-60, 2016, Peer-reviwed, In this paper, we proposed a novel strain sensor employing optical-frequency-comb cavity. The strain sensing was realized by strain/radio-frequency conversion in a fiber-based optical frequency comb cavity. The fiber-based optical frequency comb cavity generated a repetitive pulse train of which the repetition rate was determined by the cavity length. The application of mechanical strain onto the cavity produced the extension or compression of the cavity length, resulting the change of repetition rate of the pulse train. The resultant strain can be detected by observing the change of repetition rate of the pulse train with a frequency analyzer. For a proof-of-principle demonstration, we constructed an Er-doped fiber-based optical frequency comb system for the strain sensing. We demonstrated static and dynamic strain sensing with the developed system, and realized the strain sensitivity of 84.5 nε in the static strain sensing and that of 15 nε in the dynamic strain sensing with 2 m sensing fiber length. Our results demonstrated the efficacy of the strain sensor employing the optical-frequency-comb cavity.

Last, OPTICS EXPRESS, OPTICAL SOC AMER, 23, 20, 25979-25987, Oct. 2015, Peer-reviwed, An optical frequency comb interferometer with a 342-m-long fiber-based optical reference path was developed. The long fiber-based reference path was stabilized to 10-12-order stability by using a fiber noise cancellation technique, and small temperature changes on the millikelvin order were detected by measuring an interferometric phase signal. Pulse number differences of 30 and 61 between the measurement and reference paths were determined precisely, with slight tuning of the 53.4 MHz repetition frequency. Moreover, with pulse number difference of 61, a 6.4-m-wide scanning for the relative pulse position is possible only by 1 MHz repetition frequency tuning, which makes pulses overlapped for arbitrary distance. Such wide-range high-precision delay length scanning can be used to measure arbitrary distances by using a highly stabilized long fiber-based reference path. (C)2015 Optical Society of America

SCIENTIFIC REPORTS, NATURE PUBLISHING GROUP, 5, 10786:1-10786:10, Jun. 2015, Peer-reviwed, Terahertz (THz) dual comb spectroscopy (DCS) is a promising method for high-accuracy, high-resolution, broadband THz spectroscopy because the mode-resolved THz comb spectrum includes both broadband THz radiation and narrow-line CW-THz radiation characteristics. In addition, all frequency modes of a THz comb can be phase-locked to a microwave frequency standard, providing excellent traceability. However, the need for stabilization of dual femtosecond lasers has often hindered its wide use. To overcome this limitation, here we have demonstrated adaptive-sampling THz-DCS, allowing the use of free-running femtosecond lasers. To correct the fluctuation of the time and frequency scales caused by the laser timing jitter, an adaptive sampling clock is generated by dual THz-comb-referenced spectrum analysers and is used for a timing clock signal in a data acquisition board. The results not only indicated the successful implementation of THz-DCS with free-running lasers but also showed that this configuration outperforms standard THz-DCS with stabilized lasers due to the slight jitter remained in the stabilized lasers.

Lead, OPTICAL MEASUREMENT SYSTEMS FOR INDUSTRIAL INSPECTION IX, SPIE-INT SOC OPTICAL ENGINEERING, 9525, 952502, 952502-1-95250-7, Jun. 2015, Peer-reviwed, Invited, with international co-author(s), Optical Frequency combs can be used as a tool for fully controlling the phase and frequency information of light waves, i.e., "optical synthesizer". It provides powerful tools not only in frequency metrology as "ultraprecise frequency ruler" but also in broad area since light wave can be used to its full extent with an extremely wide dynamic range. Frequency-traceable length measurement using frequency combs provides direct realization of the definition of meter, remote calibration using a GPS technology, and precise measurements of wide range of lengths by taking advantage of high dynamic range in frequency measurements. In this paper, ultrahigh-precision length metrology using fiber-based optical frequency combs are presented. By precisely controlling the frequency and phase of the combs, self-correction of air refractive index and noise cancellation in fiber path in interferometer are demonstrated. Heterodyne interferometry of 61-m path-length based on two-color optical frequency combs is developed for air-refractive-index correction. Measured two-color optical-path-differences agreed with calculations with 10(-11) for 10-hour. Corrected distance variation agreed with thermal expansion of base-plate. A fiber-based optical frequency comb interferometer with 168-m-length reference path was stabilized to nm-level with fiber noise cancellation technique using a single frequency CW laser. Extremely wide range interferometric fringe scanning of 3.3-m path length was demonstrated only by tuning the repetition frequency of frequency comb without moving mechanical stage.

OPTICS EXPRESS, OPTICAL SOC AMER, 23, 9, 11367-11377, May 2015, Peer-reviwed, Real-time measurement of the absolute frequency of continuouswave terahertz (CW-THz) radiation is required for characterization and frequency calibration of practical CW-THz sources. We proposed a method for real-time monitoring of the absolute frequency of CW-THz radiation involving temporally parallel, i.e., simultaneous, measurement of two pairs of beat frequencies and laser repetition frequencies based on dual THz combs of photocarriers (PC-THz combs) with different frequency spacings. To demonstrate the method, THz-comb-referenced spectrum analyzers were constructed with a dual configuration based on dual femtosecond lasers. Regardless of the presence or absence of frequency control in the PC-THz combs, a frequency precision of 10(-11) was achieved at a measurement rate of 100 Hz. Furthermore, large fluctuation of the CW-THz frequencies, crossing several modes of the PC-THz combs, was correctly monitored in real time. The proposed method will be a powerful tool for the research and development of practical CW-THz sources, and other applications. (C) 2015 Optical Society of America

2014 39TH INTERNATIONAL CONFERENCE ON INFRARED, MILLIMETER, AND TERAHERTZ WAVES (IRMMW-THZ), IEEE, 2014, Peer-reviwed, It is crucial in asynchronous-optical-sampling THz time-domain spectroscopy or dual THz comb spectroscopy to suppress the timing jitter of the mode-locked frequency between two femtosecond lasers or frequency fluctuation of a beat signal between two THz combs because the fluctuation of them distorts the linearity of frequency scale in the spectrum. In this paper, dual THz spectrum analyzers were effectively used to extract a beat signal between dual THz combs around 0.1 THz. The resulting beat signal has a linewidth below 1Hz and a signal-to-noise ratio of 20 dB. Furthermore, the extracted beat signal was used to suppress the remained timing jitter effectively.

SCIENTIFIC REPORTS, NATURE PUBLISHING GROUP, 4, Jan. 2014, Peer-reviwed, Optical frequency combs are innovative tools for broadband spectroscopy because a series of comb modes can serve as frequency markers that are traceable to a microwave frequency standard. However, a mode distribution that is too discrete limits the spectral sampling interval to the mode frequency spacing even though individual mode linewidth is sufficiently narrow. Here, using a combination of a spectral interleaving and dual-comb spectroscopy in the terahertz (THz) region, we achieved a spectral sampling interval equal to the mode linewidth rather than the mode spacing. The spectrally interleaved THz comb was realized by sweeping the laser repetition frequency and interleaving additional frequency marks. In low-pressure gas spectroscopy, we achieved an improved spectral sampling density of 2.5 MHz and enhanced spectral accuracy of 8.39 x 10(-7) in the THz region. The proposed method is a powerful tool for simultaneously achieving high resolution, high accuracy, and broad spectral coverage in THz spectroscopy.

Last, Review of Scientific Instruments, 84, 9, 093302, Sep. 2013, Peer-reviwed, A laser-based alignment system with a He-Ne laser has been newly developed in order to precisely align accelerator units at the KEKB injector linac. The laser beam was first implemented as a 500-m-long fiducial straight line for alignment measurements. We experimentally investigated the propagation and stability characteristics of the laser beam passing through laser pipes in vacuum. The pointing stability at the last fiducial point was successfully obtained with the transverse displacements of ±40 μm level in one standard deviation by applying a feedback control. This pointing stability corresponds to an angle of ±0.08 μrad. This report contains a detailed description of the experimental investigation for the propagation and stability characteristics of the laser beam in the laser-based alignment system for long-distance linear accelerators. © 2013 AIP Publishing LLC.

Last, SCIENTIFIC REPORTS, NATURE PUBLISHING GROUP, 3, 1894 1-5, May 2013, Peer-reviwed, Optical frequency combs have become an essential tool for distance metrology, showing great advantages compared with traditional laser interferometry. However, there is not yet an appropriate method for air refractive index correction to ensure the high performance of such techniques when they are applied in air. In this study, we developed a novel heterodyne interferometry technique based on two-colour frequency combs for air refractive index correction. In continuous 500-second tests, a stability of 1.0 x 10(-11) was achieved in the measurement of the difference in the optical distance between two wavelengths. Furthermore, the measurement results and the calculations are in nearly perfect agreement, with a standard deviation of 3.8 x 10(-11) throughout the 10-hour period. The final two-colour correction of the refractive index of air over a path length of 61 m was demonstrated to exhibit an uncertainty better than 1.4 x 10(-8), which is the best result ever reported without precise knowledge of environmental parameters.

IEEE TRANSACTIONS ON TERAHERTZ SCIENCE AND TECHNOLOGY, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 3, 3, 322-330, May 2013, Peer-reviwed, The fine-structured spectrum of a terahertz (THz) frequency comb has been observed using asynchronous-optical-sampling THz time-domain spectroscopy with an extended time window covering multiple THz pulses. Fourier transformation of 10 consecutive THz pulses enables us to obtain the spectrum of THz comb mode having a linewidth of 25 MHz at intervals of 250 MHz. Further expansion of time window up to 100 consecutive THz pulses reduces the linewidth of THz comb mode down to 2.5MHz while conserving interval of 250MHz. The observed THz comb mode can be used as a precise and accurate frequency marker for broadband THz spectroscopy because it is phase-locked to a microwave frequency standard by laser control. The spectroscopy of pharmaceutical tablets and low-pressure molecular gas is used to demonstrate the utility of this approach, indicating a spectral resolution of 250 MHz. The proposed method enables frequency calibration of the THz spectrometer based on a microwave frequency standard.

Last, MEASUREMENT SCIENCE AND TECHNOLOGY, IOP PUBLISHING LTD, 24, 1, 015203_1-9, Jan. 2013, Peer-reviwed, High-accuracy two-color heterodyne interferometry based on fundamental and second harmonic of frequency combs for air refractive index correction is developed. A monitor interferometer as well as a probe interferometer is constructed to compensate the phase noises and drifts, which are caused by introducing the acousto-optic modulators for heterodyne interferometer, to realize high-accuracy measurement of optical distance. A relative stability of 10(-10) to the total length for 500 s is achieved in the measurement of an optical path length difference between two wavelengths. In long-term measurements, the interferometric measurement results and the calculations from empirical equation of air refractive indices are in good agreement with a standard deviation of 4.1 x 10(-10) throughout the 10 h period. By applying the two-color method, high-accuracy correction of air refractive index with an uncertainty of 8.9 x 10(-8) is achieved during 10 h continuous measurements while the total refractive index changes with a range of 2.0 x 10(-6).

REVIEW OF SCIENTIFIC INSTRUMENTS, AMER INST PHYSICS, 83, 5, 53301-53309, May 2012, Peer-reviwed, We experimentally investigate the focusing characteristics of a He-Ne laser at the focal region for the high-precision alignment of long-distance linear accelerators using a circular Fresnel zone plate.

The transverse displacement of the focused spot of the laser is measured as a function of the displacement of the target by a detector installed at the focal point. Systematic studies on the focusing characteristics and alignment precision have been successfully conducted in this experiment. The experimental results are in good agreement with theoretical calculations, and the alignment precision of the target is determined to be less than +/- 30 mu m. In this study, we perform a detailed experimental investigation on the laser propagation and focusing characteristics using the circular Fresnel zone plate at the focal region along with theoretical calculations.

IEEE JOURNAL OF SELECTED TOPICS IN QUANTUM ELECTRONICS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 17, 1, 191-201, Jan. 2011, Peer-reviwed, Two techniques for terahertz (THz) frequency metrology based on frequency comb, namely, a THz-comb-referenced spectrum analyzer and a continuously tunable, single-frequency continuous-wave (CW)-THz generator, are reviewed. Since the frequency comb enables to coherently link the frequency among microwave, optical, and THz regions, it is possible to establish the THz frequency metrology traceable to time of the SI base units. Using a THz-comb-referenced spectrum analyzer based on a stable THz comb generated in a photoconductive antenna for THz detection, the absolute frequency of CW test sources in the sub-THz and THz regions was determined at a precision of 10(-11). Furthermore, a continuously tunable, single-frequency CW-THz generator was demonstrated around 120 GHz by photomixing of an accurately tunable CW laser and a tightly fixed CW laser in the optical frequency region, phase locked to two independent optical combs. The combination of the CW-THz generator with the THz-comb-referenced spectrum analyzer will open the door for establishment of frequency metrology in the THz region.

OPTICS LETTERS, OPTICAL SOC AMER, 35, 10, 1689-1691, May 2010, Peer-reviwed, We constructed a fiber-based, hybrid terahertz (THz) spectrometer having two working modes, asynchronous-optical-sampling THz time-domain spectroscopy (AOS-THz-TDS) and multiple-frequency-heterodyning THz comb spectroscopy (MFH-THz-CS), by use of dual fiber-laser-based frequency combs. A spectral range of 2 THz and dynamic range of 100 was achieved at the single sweep measurement of 200 ms in the AOS-THz-TDS mode, whereas the detailed structure of the THz frequency comb was clearly observed in the MFH-THz-CS mode.

JOURNAL OF APPLIED PHYSICS, AMER INST PHYSICS, 107, 3, 033111-1-7, Feb. 2010, Peer-reviwed, A continuously tunable, phase-locked, single-frequency, continuous-wave (cw) terahertz generator has been demonstrated around 120 GHz, corresponding to the spectral bandwidth of the F-band unitraveling-carrier photodiode (UTC-PD) used as a photomixer in this study. This cw-terahertz generator is based on photomixing of an accurately tunable cw laser and a tightly fixed cw laser in the optical frequency region, phase locked to two independent optical combs. The continuous tuning range of the presented method was three orders of magnitude around 0.1 THz and two orders around 1 THz broader than that of a previous photomixing method in which two cw lasers are phase locked to a single optical comb, and fully covered the available spectral bandwidth of the F-band UTC-PD. The spectral behavior of the tight locking and continuous tuning of 120 GHz cw-terahertz radiation was confirmed in real time by use of a terahertz-comb-referenced spectrum analyzer. This cw-terahertz generator shows promise as a terahertz clock and synthesizer for terahertz frequency metrology.

OPTICS EXPRESS, OPTICAL SOC AMER, 17, 19, 17034-17043, Sep. 2009, Peer-reviwed, We propose a fiber-based, terahertz-comb-referenced spectrum analyzer which has the advantages of being a portable, alignment-free, robust, and flexible apparatus suitable for practical use. To this end, we constructed a 1550-nm mode-locked Er-doped fiber laser whose mode-locked frequency was stabilized precisely by referring to a rubidium frequency standard, and used it to generate a highly stable terahertz (THz) frequency comb in a photoconductive antenna or an electro-optic crystal. By standardizing the THz comb, we determined the frequency accuracy of an active-frequency-multiplier-chain (AFMC) source to be 2.4 x 10(-11). Furthermore, the potential of the THz spectrum analyzer was effectively demonstrated by real-time monitoring of the spectral behavior of the AFMC source and a photomixing source of two free-running CW lasers at adjacent wavelengths.

IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 58, 4, 1234-1240, Apr. 2009, Peer-reviwed, A fiber-based frequency comb has been developed to measure the frequency of a 633-nm iodine-stabilized laser at the National Metrology Institute of Japan (NMIJ). The measured frequency was consistent with the previous results measured with a Ti:sapphire-based comb. The NMIJ comb was shipped to Australia for the validation of the measurement capability of the National Measurement Institute, Australia (NMIA) and NMIJ combs using a common microwave reference and a common optical frequency. Consequently, the frequency consistency of the two combs was approximately 8 x 10(-17). Furthermore, we demonstrate that an absolute mode number of the comb can easily and clearly be determined by using the two combs.

OPTICS COMMUNICATIONS, ELSEVIER SCIENCE BV, 281, 17, 4484-4487, Sep. 2008, Peer-reviwed, We report a method for optimizing the amplification of femtosecond optical pulses by using dispersion management. The amount of dispersion provided to the seed optical pulse of an erbium-doped fiber (EBF) has an optimal region that enhances the output power of an amplifier. The power enhancement is accompanied by spectral broadening, which originates from adiabatic narrowing in the erbium-doped fiber. The amplified optical pulses can be used to generate an octave-spanning optical frequency comb (OFC) by employing a highly nonlinear fiber (HNLF). (c) 2008 Elsevier B.V. All rights reserved.

JAPANESE JOURNAL OF APPLIED PHYSICS PART 1-REGULAR PAPERS BRIEF COMMUNICATIONS & REVIEW PAPERS, INST PURE APPLIED PHYSICS, 45, 6A, 5051-5062, Jun. 2006, Peer-reviwed, An optical frequency measurement system based on an octave-spanning optical frequency comb generated by a chirped-mirror-dispersion-controlled mode-locked Ti:Al2O3 laser and a photonic-crystal fiber is developed. All of the modes-of the octave-spanning optical frequency comb are frequency-stabilized to a microwave frequency standard, where the carrier-envelope offset frequency is phase-locked with self-referencing of the comb. We investigate the methods of controlling carrier-envelope offset frequency in a chirped-mirror-dispersion-controlled mode-locked laser. The rotation of a pair of chirped mirrors is useful for setting the bias of carrier-envelope offset frequency. Although our mode-locked laser has a low pulse-repetition frequency of 150 MHz, a high signal-to-noise ratio in beats results in the direct measurement of beat frequency with a laser to be measured using a frequency counter, and enables us to phase lock carrier-envelope offset frequency merely by using a mixer analogously without the need for a prescaler, with a servo bandwidth at approximately 500 kHz. The uncertainty of our optical frequency measurement system, besides the uncertainty of microwave reference frequency, is 4 x 10(-14), and is limited by the uncertainty of the rf synthesizer used for phase locking and by that of the beat frequency measurement. Frequency measurements of an iodine-stabilized frequency-doubled Nd:YAG laser at 532 nm, an iodine-stabilized He-Ne laser at 633 nm and a rubidium two-photon-absorption stabilized extended-cavity laser diode at 778 nm are conducted. The results contributed to the revision of the practical realization of the metre adopted by the International Conference on Weights and Measures (CIPM) in 2001.

Last, OPTICS EXPRESS, OPTICAL SOC AMER, 13, 20, 8025-8031, Oct. 2005, Peer-reviwed, We demonstrate passive mode locking of solid-state lasers by saturableabsorbers based on carbon nanotubes (CNT). These novel absorbers are fabricated by spin-coating a polymer doped with CNTs onto commercial dielectric laser-mirrors. We obtain broadband artificial saturable absorber mirrors with ultrafast recovery times without the use of epitaxial growth techniques and the well-established spin-coating process allows the fabrication of devices based on a large variety of substrate materials. First results on passive mode locking of Nd:glass and Er/Yb:glass lasers are discussed. In the case of Er/Yb: glass we report the to our knowledge shortest pulse generated in a self-starting configuration based on Er/Yb: bulk-glass: 68 fs (45fs Fourier-limit) at 1570 nm wavelength at a pulse-repetition rate of 85 MHz.

Last, OPTICS LETTERS, OPTICAL SOC AMER, 30, 17, 2323-2325, Sep. 2005, Peer-reviwed, We present an arbitrary optical single-frequency generator based on a femtosecond optical frequency comb. The functions of this device are comparable to those of a radio-frequency synthesizer. However, this device operates at hundreds of terahertz. The absolute frequency accuracy of this synthesizer is similar to 1 kHz at a 282 THz carrier frequency. The stability is similar to 2 X 10(-14) at 100 s, and the tuning speed exceeds 30 GHz/s. This source demonstrates the integration of a phase-locked optical comb into a versatile and easy-to-use system for the generation of tunable, absolute optical frequencies. By using downconversion, one could generate tunable terahertz frequencies that are phase locked to a microwave reference, such as a Cs atomic clock, and high-precision interferometry could benefit greatly from the stability and accuracy of this widely tunable source.

The frequency of the hydrogen maser was calibrated with a highly stable cesium atomic clock, and therefore a fully phase-locked optical frequency comb with well-defined absolute frequencies was obtained. In contrast with the commonly used Ti:sapphire-laser-based systems, we have accomplished a fully turnkey system with no user-adjustable parts. To evaluate the performance of this novel system, we performed absolute frequency measurements in the telecommunications region and at 1064 nm and compared them with our traditional Ti:sapphire-based comb.

APPLIED OPTICS, OPTICAL SOC AMER, 43, 29, 5523-5530, Oct. 2004, Peer-reviwed, We have clarified the influences of water-vapor absorption lines in air on femtosecond pulse propagations from experimental and theoretical points of view. Precise measurements for the femtosecond pulse shapes after propagation of as much as 300 m through air have been made in a semiunderground optical testing tunnel. We observed the pulse splitting and the enhancement of the pulse broadening due to the 100-m propagation in air. The experimental results are in good agreement with the theoretical analysis by use of the HITRAN database at the edge and the center of the water-vapor absorption regions in air. Measured autocorrelation traces are mostly reproduced by those calculated with only the real part (dispersion) of the refractive index modulated by water-vapor absorption lines in air. This fact enables us to conclude that the pulse deformations due to water absorption lines in air are caused mainly by the real part (dispersion), not by the imaginary part (absorption), of the refractive index of air.

OPTICS LETTERS, OPTICAL SOC AMER, 28, 17, 1516-1518, Sep. 2003, Peer-reviwed, A frequency comb spanning more than one octave has been achieved by injecting the second-harmonic generation (780 nm) of a mode-locked fiber laser (1.56 mum) into a photonic crystal fiber. We propose and realize a novel interferometric scheme for observing the carrier-envelope offset frequency of the frequency comb. Frequency noise has been observed on the measured carrier-envelope offset frequency, which has been confirmed to be generated in the photonic crystal fiber by comparing the measured beat frequencies between cw lasers and frequency combs before and after the photonic crystal fiber. The mode-locked fiber laser is considered to be an important candidate for the light source used in realizing a compact optical frequency measurement system including applications in the telecommunication bands.

T Yasui; K Minoshima; H Matsumoto
IEEE JOURNAL OF QUANTUM ELECTRONICS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 37, 1, 12-19, Jan. 2001, Peer-reviwed, We propose a method of long-term stabilization of the repetition rate and the spectral envelope in a femtosecond mode-locked (fs-ML) laser pulse by a simple control method without modifying the laser cavity configuration. The effectiveness of the repetition-rate-stabilized fs-ML laser was evaluated in a long-optical-path (LOP) pulse interferometer with a short reference arm. The resulting accuracy in the LOP pulse interferometer was improved to one-seventh that of a free-running fs-ML laser. Moreover, the stabilization of the spectral envelope was estimated to suppress the fluctuation in the phase and group indices of an object under testing by 1/50, which can increase the measurement accuracy in pulse interferometry, The simple and practical stabilization method provides a means to increase the application of pulse interferometry using the fs-ML laser.

LASER FREQUENCY STABILIZATION, STANDARDS, MEASUREMENT AND APPLICATIONS, SPIE-INT SOC OPTICAL ENGINEERING, 4269, 95-104, 2001, Peer-reviwed, The use of an optical frequency comb generated by an ultrafast mode-locked laser has been realized as a promising method of the direct comparison between microwave and optical frequencies. We are currently investigating frequency control of a chirped-mirror-dispersion-controlled mode-locked Ti:Al2O3 laser. We stabilized the pulse repetition rate f(rep) to a rf synthesizer locked to a cesium (Cs) clock to the Allan deviation of 4 x 10(-12) in 1 s. We found that the position of the crystal, rotation of the chirped mirrors, and change of the pump-laser power can be used in controlling the carrier-envelope offset frequency f(CEO). We extended the span of the comb to over one octave, i.e., from 530 nm to 1190 nm, at -20 dB using a photonic-crystal fiber made at the University of Bath. We are currently trying to measure the frequency of an iodine-stabilized Nd:YAG laser using a floating ruler of a f:2f frequency interval chain. We detected the self-referencing beat between the fundamental and second-harmonic frequencies of the comb, which will enable further precise comparison between microwave and optical frequencies through the control of the f(CEO).

Lead, APPLIED OPTICS, OPTICAL SOC AMER, 39, 30, 5512-5517, Oct. 2000, Peer-reviwed, A high-accuracy optical distance meter with a mode-locked femtosecond laser is proposed for distance measurements in a 310-m-long optical tunnel. We measured the phase shift of the optical beat component between longitudinal modes of a mode-locked laser. A high resolution of 50 mu m at 240-m distance was obtained without cyclic error correction. The group refractive index of air is automatically extracted to an accuracy of 6 parts per million (ppm) by two-color measurement with the pulses of fundamental and second-harmonic wavelengths. Finally, an absolute mechanical distance of 240 m was obtained to within 8-ppm accuracy by use of a series of beat frequencies with the advantage of a wide range of intermode frequency, together with the results of the two-color measurement.

OPTICS COMMUNICATIONS, ELSEVIER SCIENCE BV, 183, 1-4, 181-187, Sep. 2000, Peer-reviwed, We have demonstrated optical frequency link of two frequency-stabilized laser diodes operating at 1542 nm (a rotational-vibrational line of isotope acetylene molecule) and 778 nm (an Ph two photon transition) using a two-color mode-locked fiber laser. The laser produces a frequency comb (300 fs pulse) in the 1560 nm region and, through the second harmonic generation (SHG) process, another frequency comb (100 fs pulse) in the 780 nm region. Beat note signals have been observed between each of the stabilized laser radiation and a mode of the mode-locked fiber laser in the vicinity of the stabilized laser frequency. The S/N ratios were 25 dB and 30 dB with 100 kHz resolution bandwidth for brat notes at lambda = 1542 nm and lambda = 778 nm, respectively. Preliminary result has shown the potential of the system for frequency measurements with the accuracy of below 100 kHz. This limitation will be overcome by improving the frequency counting system using a phase-locked tracking oscillator and installing a PZT element in the fiber laser cavity, Supposing the accuracy of the mode spacing is similar to the case of a mode-locked Ti:sapphire laser, the accuracy of kHz level is very presumable.

It is found that the optical Kerr effect and the amplification process in the fs-amp OKG do not cause the quality of a time-resolved image to deteriorate. We prove the effectiveness of the proposed system by measuring the shapes of completely diffusing objects with stepped and spherical surfaces.

APPLIED PHYSICS LETTERS, AMER INST PHYSICS, 74, 14, 2062-2064, Apr. 1999, Peer-reviwed, We report the generation and characterization of the self-pumped phase conjugation of 450 nm femtosecond pulses in BaTiO3. The pump beam is incident on the crystal from the -c face of the crystal. We suggest that the transmission grating exclusively contribute to the self-pumped phase conjugation and that the femtosecond self-pumped phase conjugator operate with a mechanism of holographic grating sharing. The self-pumped phase conjugate pulses are narrower than the transmitted pulses. The pulse width of the self-pumped phase conjugation increases as the incident angle. The angular dispersion caused by the air crystal interface and the dynamic gratings compensates for the material dispersion of the crystal, leading to narrower reflected pulses from the phase conjugator.

APPLIED OPTICS, OPTICAL SOC AMER, 38, 9, 1704-1708, Mar. 1999, Peer-reviwed, Ne demonstrate a new configuration of self-pumped phase conjugation in BaTiO3 with 450-nm femtosecond pulses. The pump beam enters the -c face of the crystal at an acute angle with respect to the +c ards. This geometry is different from all known geometries of self-pumped phase conjugations in BaTiO3. Phase-conjugate reflectivity of 1.7% and a rise time of similar to 24 s are obtained at an average pump power of 10 mW. The ability of the phase conjugator to serve phase distortions correctly is demonstrated. Ne propose that the femtosecond phase conjugator operate with the hologram mechanism sharing as the double phase conjugator. The self-pumped phase-conjugate pulses are analyzed by femtosecond electric-field cross correlation. (C) 1999 Optical Society of America.

CLEO/Pacific Rim 1999 - Pacific Rim Conference on Lasers and Electro-Optics, Institute of Electrical and Electronics Engineers Inc., 3, 761-762, 1999, Peer-reviwed, In order to obtain a high depth resolution, not only the use of a fast shutter, but also the use of a fast modulated chirped pulse is necessary. A chirped pulse of wide spectrum range is necessary, therefore a wide band shutter is also needed. Shutters faster than CS2 were realized using other materials such as glasses or organic dyes. We applied the technique of fast shutter, which uses optical Kerr effect in gain medium and two perpendicularly polarized pump pulses in the picosecond region, to the femtosecond region, successfully. The technique made possible a femtosecond amplifying optical Kerr gate. A setup for ultra time-resolved spectroscopic imaging is shown. The experimental result shows that the peak transmission of 160%, which is more than 20 limes larger than that of the conventional CS2 Kerr gate. The transient spectra with regard to each delay time are about 60 nm. Using this new technique, ultrafast time-gated spectroscopic imaging is experimentally achieved.

CLEO/Pacific Rim 1999 - Pacific Rim Conference on Lasers and Electro-Optics, Institute of Electrical and Electronics Engineers Inc., 3, 765-766, 1999, Peer-reviwed, Recently, femtosecond optical lasers have become popular in several fields of application. Up to now, because the ultrashort laser has been large and complex, it had not been used in practical applications. However, very recently, several types of compact femtosecond lasers have been developed, thanks to the improvement of solid-state laser techniques. In particular, the development ofa palm-top fiber laser has opened the door to real-world applications, such as distance measurements in open fields. A distance meter with a laser is useful because noncontact measurement is possible. Conventionally, continuous-wave lasers have been used for distance measurements, together with intensity modulation or interferometric techniques. The interferometric technique has the advantage that high resolution is possible, but simultaneously, it is too sensitive to environmental fluctuation or vibration. The modulation technique can enable stable measurement, even in an open field, but it requires rather complex setups to achieve high frequency modulation. High-frequency modulation is necessary for realizing high resolution because under most conditions, the measurement resolution is limited by the resolution of the phase meter, and thus higher frequency leads to higher resolution for the same smallest phase unit. The complexity of the setup causes nonlinear error originating from light reflections from the boundary surfaces of the optical components. In this paper, we propose a new high-accuracy optical distance meter with a mode-locked femtosecond laser.

OPTICAL MANUFACTURING AND TESTING III, SPIE-INT SOC OPTICAL ENGINEERING, 3782, 559-566, 1999, Peer-reviwed, For real-time 3D imaging using chirped optical pulses and a femtosecond optical Kerr shutter to measure the shape accurately, we need to develop a spectral imaging method which has a high-resolution in both space and spectrum. The spectral property of the light which is generated from the chirped pulse by the femtosecond optical Ken shutter, the wavelength is measured as the line spectrum. Therefore, the wavelength can be determined by two detectors with different spectral properties. To obtain the line spectral image, we proposed a pair of filters, the transmissivities of which vary monotonously with the wavelength, one increases with the wavelength, the other decreases. Since the ratio between the transmissivities of the two filters changes monotonously for wavelength range of 550 - 750 Mn, the wavelength of line spectrum is determined uniquely for the range with a Simple function of the ratio. These filters were set in front of two monochromatic CCDs which are aligned to take an image. The resolution to determine the wavelength is tested with a monochrometer and the standard deviation for each pixel is estimated to be about 10 nm. Compared the methods of color CCD and spectrometer, this method of pair-CCDs has high spatial resolution, uniform spectral resolution, wide spectral measurement range, and simple setup.

CHEMICAL PHYSICS, ELSEVIER SCIENCE BV, 219, 1, 73-89, Jun. 1997, Peer-reviwed, Picosecond streak camera measurements, time-resolved absorption and reorientation time measurements (by optical Kerr effect) of push-pull diphenyl-polyenes (4-dimethylamino 4'-cyano stilbene: DCS, 1-(p-N,N-dimethylamino)-4-(p-cyanophenyl)-1,3-butadiene: DCB) in solution have revealed, in polar solvents at high concentration and high excitation intensity, the presence of a new emitting species characterized by an anomalous red-shifted fluorescence band. The formation rate and the excited state decay time of the new species is measured for the first time at room temperature as well as the spectral characteristics of the fluorescence. The intensity of the new fluorescence band has been found to be proportional to the square of the excitation intensity. Furthermore, the reorientation time at high concentration has been determined to be nearly twice as long as that at low concentration, indicating the possibility of the formation of complexes in the ground state with nearly twice the molecular volume compared with the monomer. This bimolecular and biphotonic process, demonstrated by the experimental results, makes it possible to reveal a 'loose' complex formation in the ground state, leading upon high excitation intensity to the new emitting species already called 'bicimer' in preliminary studies and formed by the association of two electronically excited molecules.

The instantaneous response in the time-resolved difference transmission spectrum including the inverse Raman, induced and saturated absorption was successfully reproduced by the calculation under sub-resonant excitation based on the density matrix formalism.

This technique is applicable for imaging of the shape of moving objects, or surface testing or inspection.

Difference absorption spectra due to the Kerr effect were induced by changes in a static dipole moment and a polarizability separated by the dual-phase lock-in detection. The change in the static dipole moment associated with the transition from the ground state to the exciton state was measured with an applied ac field (F) of 300 Hz and polarization (e) parallel and perpendicular to the one-dimensional axis (d) of the oriented J-aggregates, and obtained in each configuration to be 18 (F parallel-to d/e parallel-to d), 12 (F perpendicular-to d/e parallel-to d), 27 (F parallel-to d/e perpendicular-to d), and 14 (F perpendicular-to d/e perpendicular-to d) D.

Lead, CHEMICAL PHYSICS LETTERS, ELSEVIER SCIENCE BV, 218, 1-2, 67-72, Feb. 1994, Peer-reviwed, Time-resolved difference absorption spectra of J-aggregates were measured by femtosecond pump-probe spectroscopy. The induced absorption near the J-band at 20 K was assigned to the transitions from n-exciton states to (n = 1)-exciton states (n equal to or greater than 1). The decay time of the n(equal to or greater than 2)-exciton states is determined to be about 200 fs. The ultrafast dynamics of the exciton states is explained by a confined exciton model in individual coherent aggregates, which incoherently constitute the whole structural aggregate. The average size of the exciton system defined for each coherent aggregate is estimated to be about 20 molecules.

Linear dichroic spectra of the oriented J aggregate of 1,1'-diethyl-2,2'-quinocyanine bromide PIC-Br were measured at 5 K. The dichroic ratio at the peak of J band was 5 to 10, dependent on the preparation conditions. Precise measurement of the dichroism at the J band revealed that the J band is composed of two bands with transition dipole moments perpendicular to each other. The films are stable even at room temperature, and have applications as nonlinear optical devices.

Copyright © 2018 SPIE. Refractive index measurement is important for evaluation of liquid materials, optical components, and bio sensing. One promising approach for such measurement is use of optical fiber sensors such as surface plasmonic resonance or multi-mode interference (MMI), which measure the change of optical spectrum resulting from the refractive index change. However, the precision of refractive index measurement is limited by the performance of optical spectrum analyzer. If such the refractive index measurement can be performed in radio frequency (RF) region in place of optical region, the measurement precision will be further improved by the frequency-standard-based RF measurement. To this end, we focus on the disturbance-to-RF conversion in a fiber optical frequency comb (OFC) cavity. Since frequency spacing frep of OFC depends on an optical cavity length nL, frep sensitively reflects the external disturbance interacted with nL. Although we previously demonstrated the precise strain measurement based on the frep measurement, the measurable physical quantity is limited to strain or temperature, which directly interacts with the fiber cavity itself. If a functional fiber sensor can be installed into the fiber OFC cavity, the measurable physical quantity will be largely expanded. In this paper, we introduce a MMI fiber sensor into a ring-type fiber OFC cavity for refractive index measurement.

A statement error was produced in the text introducing the previous literatures in [Opt. Express 25, 11910 (2017)]. Here, we correct this error and clarify that this is only due to the simple editing mistake, not related to the scientific misunderstanding about the referenced literatures. Thus, all the conclusions written in [Opt. Express 25, 11910 (2017)1 remain unchanged by this correction.

© 2017 SPIE. Photo-acoustic imaging is a promising modality for deep tissue imaging with high spatial resolution in the field of biology and medicine. High penetration depth and spatial resolution of the photo-acoustic imaging is achieved by means of the advantages of optical and ultrasound imaging, i.e. Tightly focused beam confines ultrasound-generated region within micrometer scale and the ultrasound can propagate through tissues without significant energy loss. To enhance the detection sensitivity and penetration depth of the photo-acoustic imaging, highly sensitive ultrasound detector is greatly desired. In this study, we proposed a novel ultrasound detector employing optical frequency comb (OFC) cavity. Ultrasound generated by the excitation of tightly focused laser beam onto a sample was sensed with a part of an OFC cavity, being encoded into OFC. The spectrally encoded OFC was converted to radio-frequency by the frequency link nature of OFC. The ultrasound-encoded radio-frequency can therefore be directly measured with a high-speed photodetector. We constructed an OFC cavity for ultrasound sensing with a ring-cavity erbium-doped fiber laser. We provided a proof-of-principle demonstration of the detection of ultrasound that was generated by a transducer operating at 10 MHz. Our proposed approach will serve as a unique and powerful tool for detecting ultrasounds for photo-acoustic imaging in the future., 01 Jan. 2017, Progress in Biomedical Optics and Imaging - Proceedings of SPIE, 10064, 1605-7422, 85018866599 - Optical-frequency-comb based ultrasound sensor

We constructed a widely and continuously tunable terahertz frequency synthesizer traceable to a microwave frequency standard. Photomixing of two optical frequency synthesizers, linked to the frequency standard via dual optical frequency combs, makes this THz synthesizer traceable to the frequency standard. To demonstrate the potential of wide and continuous tunability in the THz synthesizer, we tuned its output frequency by 120 GHz continuously around 0.65 THz by using a uni-traveling-carrier photodiode as a photomixer and applied it for precise THz spectroscopy of low-pressure molecular gas. This THz synthesizer will be a powerful tool for broadband, high-precision THz spectroscopy., IEEE, 2014, 2014 39TH INTERNATIONAL CONFERENCE ON INFRARED, MILLIMETER, AND TERAHERTZ WAVES (IRMMW-THZ), English, Peer-reviwed, 2162-2027, 46555285, 84911980090, WOS:000378889200121 - 「光周波数コム」が拓く新しい光の世界

Methods of photonic device fabrication and characterization that have been made possible by recent advances in femtosecond laser technology are described. Femtosecond laser oscillators enable significant improvement in fabrication speeds compared with amplifiers. The oscillators are more convenient, less expensive and offer pulse repetition rates that are much higher than those of standard femtosecond amplifiers., Optical Society of America (OSA), 2003, Optics and Photonics News, 14, 5, 44-49, English, Introduction other, 1047-6938, 0141868863 - 解説 フェムト秒レーザの簡易安定化技術--フェムト秒パルス干渉法の高精度化を目指して
