Tatsuya Ohtsuki; Motoharu Matsuura
IEEE Photonics Technology Letters, Institute of Electrical and Electronics Engineers Inc., 30, 5, 459-462, 01 Mar. 2018, Peer-reviwed, We demonstrate all-optical wavelength conversion of a 4-level pulse-amplitude modulation (PAM-4) signal by cross gain modulation (XGM) in a quantum-dot semiconductor optical amplifier (QD-SOA). In this scheme, the center passband of a conventional optical filter located at the QD-SOA output is slightly shifted to the shorter wavelength side [blue-shifted filtering (BSF)], which enables us to accelerate the gain recovery time of the QD-SOA and reduce the bandwidth limitation in the process of the wavelength conversion. By using the combination of XGM and BSF, we successfully achieve 25-Gbit/s PAM-4 wavelength conversion, with good conversion performance in terms of error-vector magnitude. We also investigate the conversion performance in a wide wavelength-hopping range and the high tolerance to the shift in input signal wavelength for use in data center applications.

Optically powered radio-over-fiber system based on center- and offset-launching techniques using a conventional multimode fiber
Hayao Kuboki; Motoharu Matsuura
OSA Optics Letters, OSA - The Optical Society, 43, 5, 1067-1070, 01 Mar. 2018, Peer-reviwed, We demonstrate radio-over-fiber (RoF) transmission with a 10-W feed power-over-fiber (PWoF) using a conventional multimode fiber (MMF). In this scheme, the modal dispersion and feed light crosstalk in the MMF are effectively mitigated by the combination of center-launching (CL) and offset-launching (OL) techniques. The CL is used for propagating the feed light into lower-order modes in the MMF, while the OL is used not only for propagating the optical data signals into higher-order modes in the MMF, but also for mitigating the modal dispersion. We successfully achieved significant improvement in the RoF transmission performance with the 10-W feed PWoF and extended the link length up to 4 km, owing to the two techniques.

Composite Effect of E/O Nonlinearity and Optical Echo on EPWM-OFDM Transmission in Radio Over Fiber Channel
Xiaoxue Yu; Motoharu Matsuura; Yasushi Yamao
WIRELESS PERSONAL COMMUNICATIONS, SPRINGER, 93, 3, 647-660, Apr. 2017, Peer-reviwed, Radio over Fiber (RoF) is a promising technology for extending broadband wireless access to indoor and outdoor dead spots. However, commonly applied intensity-modulation / direct-detection RoF transmission presents some nonlinearity and produces echo distortion. Since multiple carrier modulation signals such as Orthogonal Frequency Division Multiplexing (OFDM) are widely employed in broadband wireless systems, the above issues become more serious. The OFDM signals have high Peak-to-Average Power Ratio, which makes them more sensitive to nonlinearity. Moreover, the large delay of optical echoes that are caused by the discontinuity of refractive index at both ends of Electrical/Optical (E/O) and Optical/Electrical converters exceeds the guard time of current OFDM symbols when the length of optical fiber is long. Since the nonlinearity and echo exist simultaneously in RoF channels, their composite effect is mathematically analyzed in this paper. A RoF-echo model is proposed for the modeling of the multiple light reflections and its validity is confirmed by experiments. Then, Envelop-Pulse-Width-Modulation- (EPWM-) RoF transmission is proposed for dealing with the nonlinearity and echo in RoF channel. The performance of the EPWM-RoF scheme for OFDM signal transmission is evaluated by simulations, which reveals that the scheme improves the transmission quality in Error Vector Magnitude under the composite environment of E/O nonlinearity and optical echo.

Optically Powered and Controlled Beam Steering System for Radio-Over-Fiber Networks
Motoharu Matsuura; Yamato Minamoto
Lead, IEEE/OSA Journal of Lightwave Technology, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 35, 4, 979-988, Feb. 2017, Peer-reviwed, Invited, This study presents an optically powered and controlled beam steering system for radio-over-fiber networks. The beam steering technique is based on optical multicasting and true-time delay among the multicast signals for a remote antenna unit. The power required for driving the entire remote antenna unit is delivered from a central office to the remote antenna unit by power-over-fiber technique using double-clad fibers, which consist of a single-mode core and an inner-cladding that surrounds the single-mode core. In the fiber link, an optical data signal is transmitted into the single-mode core without limiting the signal bandwidth because of modal dispersion, whereas high-power feed light for optical powering is transmitted into the inner-cladding with a core effective area that is much larger than the single-mode core. To show the feasibility of the beam steering system, we have experimentally evaluated the signal performance of beam steering for a 60-W power-over-fiber feed using a 300-m double-clad fiber link in terms of error-vector magnitude measurements. We have successfully achieved good signal performances for various beam angles estimated using true-time delay settings for multicast signals.

IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E99C, 2, 227-234, Feb. 2016, Peer-reviwed, We experimentally investigate the performance of a distributed Raman amplifier (DRA)-based pulse compressor for a phase modulated signal. A 10 Gb/s return-to-zero (RZ)-differential phase shift keying (DPSK) signal is compressed to picosecond range after transmission. Pulsewidth is continuously compressed in a wide range from 20 to 3.2 ps by changing the pump power of the DRA while the compressed waveforms are well-matched with sech(2) function. Error-free operations at bit-error-rate (BER) of 10(-9) are achieved for the compressed signals of various pulsewidths with low power penalties within 2.3 dB compared to the back-to-back. After the compression, the 10 Gb/s signal is used to generate a 40 Gb/s RZ-DPSK optical time division multiplexing (OTDM) signal. This 40 Gb/s OTDM signal is then successfully demultiplexed to 10 Gb/s DPSK signal by using an optical gate based on four-wave mixing (FWM) in a highly nonlinear fiber (HNLF).

All-optical pulsewidth-tunable wavelength conversion of return-to-zero differential phase-shift keying signal
Gazi Mohammad Sharif; Quang Nguyen-The; Motoharu Matsuura; Naoto Kishi
OPTICAL REVIEW, OPTICAL SOC JAPAN, 22, 4, 553-559, Aug. 2015, Peer-reviwed, We demonstrate the wavelength conversion of return-to-zero differential phase-shift keying (RZ-DPSK) signal with the pulsewidth-tunable operation using a Raman amplifier (RA)-based ultrashort pulse compressor and a highly nonlinear fiber (HNLF)-based four-wave mixing (FWM) switch. The wavelength of the input RZ-DPSK signal is converted to new wavelengths owing to the FWM effect in HNLF. On the other hand, the pulsewidth of the wavelength-converted RZ-DPSK signal is tuned from 10 to 3 ps by using the ultrashort pulse source based on RA-based adiabatic soliton pulse compression. The bit error rate characteristics of the input RZ-DPSK and the wavelength-converted RZ-DPSK signals with different pulsewidths are measured and error-free operations are achieved in all cases. The optical spectra, autocorrelation traces, and clear and opening eye diagrams show high conversion performance with wide-range pulsewidth tunability.

IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E98C, 8, 816-823, Aug. 2015, Peer-reviwed, All-optical 1-to-6 wavelength multicasting of a 10-Gb/s picosecond-tunable-width converted return-to-zero (RZ)-on-off-keying (OOK) data signal using a wideband-parametric pulse source from a distributed Raman amplifier (DRA) is experimentally demonstrated. Width-tunable wavelength multicasting within the C-band with approximately 40.6-nm of separation with various compressed RZ data signal inputs have been proposed and demonstrated. The converted multicast pulse widths can be flexibly controlled down to 2.67 ps by tuning the Raman pump powers of the DRA. Nearly equal pulse widths at all multicast wavelengths are obtained. Furthermore, wide open eye patterns and penalties less than 1.2 dB at the 10-9 bit-error-rate (BER) level are found.

IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E98C, 8, 824-831, Aug. 2015, Peer-reviwed, A combination of nonreturn-to-zero (NRZ)-to-return-to-zero (RZ) waveform conversion and wavelength multicasting with pulsewidth tunability is experimentally demonstrated. A NRZ data signal is injected into a highly nonlinear fiber (HNLF)-based four-wave mixing (FWM) switch with four RZ clocks compressed by a Raman amplification-based multiwavelength pulse compressor (RA-MPC). The NRZ signal is multicast and converted to RZ signals in a continuously wide pulsewidth tuning range between around 12.17 and 4.68 ps by changing the Raman pump power of the RA-MPC. Error-free operations of the converted RZ signals with different pulsewidths are achieved with negative power penalties compared with the back-to-back NRZ signal and the small variation among received powers of RZ output channels at a bit-error-rate (BER) of 10-9. The NRZ-to-RZ waveform conversion and wavelength multicasting without using the RA-MPC are also successfully implemented.

OPTICAL REVIEW, OPTICAL SOC JAPAN, 22, 3, 489-495, Jun. 2015, Peer-reviwed, For the first time, we demonstrated a wide range operation of an all-optical non-return-to-zero (NRZ)-differential-phase-shift-keying (DPSK)-to-return-to-zero (RZ)-DPSK waveform-wavelength conversion with flexible picosecond width-tunablity and regenerative functionality. The scheme is based on a Raman amplifier soliton compressor (RASC) and a fiber-based four-wave mixing (FWM) AND-gate. In the first demonstration, we demonstrated waveform-wavelength conversion of a 10-Gb/s DPSK signal without input signal degradation over 54-nm input-output wavelength ranges. The measurement results of the converted RZ-DPSK signal are pedestal-free, and its converted pulse width from 13.0 to 2.87-ps can be adjusted by tuning the Raman pump power between 0.20 and 0.90 W. An investigation of the regenerative waveform-wavelength conversion is further conducted at different Raman pump power settings over 40-km standard single-mode fibers without dispersion compensation. Error-free operation with a low power penalty less than -1.95 dB is obtained for the RZ-DPSK regenerated converted signal.

Bidirectional Radio-Over-Fiber Systems Using Double-Clad Fibers for Optically Powered Remote Antenna Units
Motoharu Matsuura; Jun Sato
IEEE Photonics Journal, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 7, 1, 1-9, Feb. 2015, Peer-reviwed, This paper shows and experimentally demonstrates bidirectional radio over fiber (RoF) using a double-clad fiber (DCF) for optically powered remote antenna units (RAUs). The DCF for an RoF link has a single mode (SM) core and a multimode inner cladding; the SM core is used for simultaneous downlink and uplink transmissions of the optical RoF data signals, whereas the inner cladding is used for optical power delivery to the RAU. The aim of this approach is to optically power the RAU in such a way that external electrical power supplies, such as batteries or public power lines, are not required. The feasibility of the technique is demonstrated by bidirectional RoF transmission over a 100-m DCF optically feeding with 4.0 W. We successfully achieved high downlink and uplink transmission performance in terms of error vector magnitude measurements, which are based on the IEEE 802.11g wireless local area network (WLAN) standard at a carrier frequency of 2.45 GHz.

Performance of a routing and wavelength assignment scheme for an optical-carrier-reusable ring network
Masafumi Keri; Nattapong Kitsuwan; Motoharu Matsuura; Eiji Oki
IET Networks, Institution of Engineering and Technology, 3, 4, 267-274, 01 Dec. 2014, Peer-reviwed, This study investigates a heuristic routing and wavelength assignment (RWA) scheme for an optical-carrier-reusable ring network. This network has two unique features. First, only one light source, called the multi-carrier light source, is required which eases the difficulty of controlling many light source devices. Second, optical carriers are reused in order to improve the efficiency of wavelength usage. Given the target of wavelength-resource-efficient channel establishment, performance of the heuristic RWA scheme is evaluated. To realise efficient wavelength usage, the authors formulate the RWA problem as an integer linear programming (ILP) problem of obtaining the minimum number of required wavelengths for given requests. With the ILP approach, the calculation process is not tractable in practical time. The heuristic RWA scheme introduced in this study solves the RWA problem. This scheme consists of two algorithms. Channel routes are obtained by the routing algorithm, and the wavelength assignment algorithm is then performed to assign a wavelength to each route. Moreover, two candidates, considering the shortest path and considering the avoidance of wavelength conversion, for the routing algorithm are examined. Numerical results show that the first candidate is more suitable in terms of reducing the number of required wavelengths than the second candidate.

All-Optical Wavelength-Shift-Free NRZ-DPSK to RZ-DPSK Format Conversion with Pulsewidth Tunability by an SOA-Based Switch
Gazi Mohammad Sharif; Quang Nguyen-The; Motoharu Matsuura; Naoto Kishi
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E97C, 7, 755-761, Jul. 2014, Peer-reviwed, We demonstrate an all-optical non-return-to-zero differential phase shift keying (NRZ-DPSK) to return-to-zero differential phase shift keying (RZ-DPSK) format conversion with wavelength-shift-free and pulsewidth tunable operations by using a semiconductor optical amplifier (SOA)-based switch. An NRZ-DPSK signal is injected into the SOA-based switch with an RZ clock, and is converted to RZ-DPSK signal owing to the nonlinear effects inside the SOA. In this scheme, the wavelength of the converted RZ-DPSK signal is maintained as the original wavelength of the input NRZ-DPSK signal during the format conversion. Moreover, the pulsewidth of the converted signal is tunable in a wider operating range from 30 to 60 ps. The format conversion with pulsewidth tunability is based on cross-phase modulation (XPM) and cross-gain modulation (XGM) effects in the SOA. The clear eye diagrams, optical spectra and the bit-error-rate (BER) characteristics show high conversion performance with the wide pulsewidth tuning range. For all cases of the converted RZ-DPSK signal with different pulsewidths, the receiver sensitivities at a BER of 10(-9) for the converted RZ-DPSK signal were 0.7 to 1.5 dB higher than the receiver sensitivity of the input NRZ-DPSK signal.

Reflection noise reduction effect of graded-index plastic optical fiber in multimode fiber link
Azusa Inoue; Rei Furukawa; Motoharu Matsuura; Yasuhiro Koike
OPTICS LETTERS, OPTICAL SOC AMER, 39, 12, 3662-3665, Jun. 2014, Peer-reviwed, We experimentally demonstrate that a graded-index plastic optical fiber (GI POF) can significantly reduce reflection noise in a multimode fiber link with a vertical-cavity surface-emitting laser (VCSEL). By directly observing beams backreflected to the VCSEL, we show that the noise reduction effect is closely related to random mode coupling because of light scattering by microscopic heterogeneities in the GI POF core material. This suggests that intrinsic mode coupling can lower the self-coupling efficiency of the light backreflected to the VCSEL cavity through beam quality degradation. Using GI POFs, low-cost radio-over-fiber systems for indoor networks can be realized without optical isolators or fiber end-face polishing. (C) 2014 Optical Society of America

Motoharu Matsuura; Rei Furukawa; Yuki Matsumoto; Azusa Inoue; Yasuhiro Koike
OSA Optics Express, OPTICAL SOC AMER, 22, 6, 6562-6568, Mar. 2014, Peer-reviwed, We have evaluated and compared modal noise induced in a graded-index silica multimode fiber (GI-MMF) link and a graded-index plastic optical fiber (GI-POF) link with the misaligned fiber connections. In radio over fiber (RoF) systems using these optical fibers, modal noise appears as unwanted amplitude modulation in the received signal, and results in degradation of the RoF transmission performance. In this work, we have evaluated the modal noise induced in GI-MMFs and GI-POFs with its same core diameter of 50 mu m. Our results show that GI-POFs have an inherently higher tolerance to misaligned connection and less modal noise than GI-MMFs in terms of both the error-vector magnitude and the speckle pattern of the transmitted signals.

EPWM-OFDM Signal Transmission against Nonlinearities of E/O Converters in Radio over Fiber Channel
Xiaoxue Yu; Yasushi Yamao; Motoharu Matsuura
IEICE TRANSACTIONS ON COMMUNICATIONS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E97B, 2, 484-494, Feb. 2014, Peer-reviwed, Radio over Fiber (RoF) is a promising technology that is suitable for broadband wireless access systems to cover in-building areas and outdoor dead-spots. However, one issue in RoF transmission that should be considered is the nonlinear distortion caused by Electrical/Optical (E/O) converters. Multicarrier RF (Radio Frequency) signal formats such as Orthogonal Frequency Division Multiplexing (OFDM), which are commonly employed in broadband wireless communications, are weak against nonlinearities. To enable the linear transmission of OFDM signal in RoF channel, we propose to employ the Envelop Pulse Width Modulation (EPWM) transmission scheme for RoF channel. Two commonly used E/O converters, Mach-Zehnder modulator and direct-modulation of Distributed Feedback Laser Diode (DFB LD), are employed to validate the proposal. Based on the measured nonlinearities of the E/O converters, they are mathematically modeled and their transmission performance are analyzed. A modified Rapp model is developed for the modeling of the DFB LD. Through simulations and experiments, the proposed scheme is shown to be effective in dealing with the nonlinearities of the E/O converters.

Use of state of polarization transparent scheme for polarization shift keying signal as optical phase conjugator to improve the transmission performance
Md Nur-Al-Safa Bhuiyan; Motoharu Matsuura; Hung Nguyen Tan; Naoto Kishi
OPTICAL REVIEW, OPTICAL SOC JAPAN, 21, 1, 48-53, Jan. 2014, Peer-reviwed, Transmission characteristics of polarization shift keying (PolSK) signal is experimentally demonstrated in this work. Performance degradation due to transmission is improved using optical phase conjugation (OPC) technique. The wavelength converter based on the proposed state of polarization (SOP) transparent scheme for PolSK signal is effective to use it as mid-link optical phase conjugator and which is difficult to achieve using conventional wavelength conversion scheme. It is found that for fiber transmission, the performance of both of the orthogonal SOPs of the PolSK signal is different for their respective chirping characteristics which can be optimized to be similar using proposed OPC technique.

Power-Over-Fiber Using Double-Clad Fibers for Radio-Over-Fiber Systems
Motoharu Matsuura; Jun Sato
2014 19TH EUROPEAN CONFERENCE ON NETWORKS AND OPTICAL COMMUNICATIONS - (NOC), IEEE, 126-131, 2014, Peer-reviwed, This work presents a power-over-fiber (PoF) using double-clad fibers (DCFs) for radio-over-fiber (RoF) systems. The DCF for the RoF link has a single-mode (SM) core and a multimode inner cladding; the SM core is used for both downlink and uplink transmissions of the optical RoF data signals, while the inner cladding is used for optical power delivery to the BS. The aim of this approach is to optically power the BS in such a way that external electrical power supplies such as batteries or public power lines are not required. The feasibility of the technique is demonstrated by RoF transmission over a 100-m DCF optically feeding with 4.0 W. We successfully achieved high downlink and uplink transmission performances from the CS to the BS in terms of bit-error rate and error-vector magnitude measurements, based on the IEEE 802.11g wireless local area network standard at a carrier frequency of 2.45 GHz.

As a result, the full true time delay was obtained by adjusting the dispersion value of the tunable dispersion medium (TDM) from 400 ps/nm to +400 ps/nm. We successfully achieved the high TTD performance for various output beam angles.

Rei Furukawa; Morio Nagata; Kenji Mishima; Motoharu Matsuura; Azusa Inoue; Akihiro Tagaya; Yasuhiro Koike
APPLIED PHYSICS LETTERS, AMER INST PHYSICS, 103, 21, 213301, Nov. 2013, Peer-reviwed, Poly-(methyl methacrylate-co-benzyl methacrylate) polarization-maintaining optical fibers are known for their high response to normal stress. In this report, responses to higher stress levels up to 0.45 MPa were investigated. The stress amplitude and direction in the fiber cross section were calculated and analyzed with a coincident mode-field obtained from the near-field pattern. The stress amplitude varies significantly in the horizontal direction and is considered to create multiple phases, explaining the measurement results. To investigate possible permanent deformation, the core yield point profile was analyzed. Although it largely exceeds the average applied stress, the calculated stress distribution indicates that the core could partially experience stress that exceeds the yield point.

All-optical polarization-insensitive non-return-to-zero-to-pulsewidth tunable return-to-zero conversion
Gazi Mohammad Sharif; Quang Nguyen-The; Motoharu Matsuura; Naoto Kishi
OPTICAL REVIEW, OPTICAL SOC JAPAN, 20, 3, 266-270, May 2013, Peer-reviwed, We demonstrate polarization-insensitive non-return-to-zero (NRZ)-to-pulsewidth tunable return-to-zero (RZ) conversion based on a Raman amplifier (RA)-based pulse compressor and a fiber-based NRZ-to-RZ converter, which consists of a polarization diversity loop. We measure the bit-error rate (BER) characteristics of the input NRZ signal and the converted RZ signals. The power penalty of less than 0.2 dB between the converted RZ signals with different power ratios proved the polarization insensitivity. Moreover, by changing the Raman pump power of the RA-based pulse compressor, the pulsewidths of the converted RZ signals were flexibly tuned from 10 to 2 ps, which proved NRZto-RZ conversion with pulsewidth tunability. In all cases, clear eye diagrams were obtained. (C) 2013 The Japan Society of Applied Physics

Scalability Analysis and Demonstration of Distributed Multicarrier Reusable Network With Optical Add/Drop Multiplexers
Motoharu Matsuura; Eiji Oki
2013 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS (ICC), IEEE, 3889-+, 2013, Peer-reviwed, We demonstrate a distributed multicarrier reusable network (DMRN) for regional and metro areas, based on dense wavelength-division multiplexing (DWDM) transmission with reconfigurable optical add/drop multiplexers (ROADMs). To eliminate the multiple distributed laser-diodes (LDs) at each access node in conventional ROADM networks, optical carriers generated by a centralized multicarrier light source (MCLS) are distributed to the access nodes, and they are used for node-tonode data transmission. The ROADM employed at each access node is used not only to "add" and "drop" data, but also to "drop" optical carriers. Moreover, to improve the wavelength utilization efficiency of the carriers distributed by the MCLS in the network, we proposed a technique called optical carrier regeneration (OCR), whereby the distributed carriers can be reused in each access node. This technique has a simple scheme and enables us to reuse the carriers that were already utilized for data transmission between prior source and destination nodes.
In this work, we numerically analyze the scalability of our proposed DMRN in terms of the number of nodes, the span length, and the cascadability of the OCR. Moreover, we conduct a DMRN experiment using 10.7 Gb/s x 4 channels DWDM transmission and compare the transmission performances for various span lengths, for the first time. The results show that the DMRN will be useful for wide-area metro networks with high transmission performances.

OPTICAL SWITCHING AND NETWORKING, ELSEVIER SCIENCE BV, 9, 4, 336-342, Nov. 2012, Peer-reviwed, We demonstrate in an experiment an optical packet switching (OPS) using recursive parametric wavelength converters (PWCs) which uses the combination of two or more PWCs for wavelength conversions. The PWCs, which are based on four-wave mixing in highly nonlinear fibers, are possible for multiple wavelength conversion, allowing a shareper-node switching scheme, and thus significantly reducing the number of wavelength converters. Detailed demonstration of a developed OPS prototype using the joint of two PWCs indicates the generation of various wavelength conversion patterns which play an important role for OPS performance. The converted signals after two stages of PWC are obtained with error-free operations and low power penalties (BER = 10(-9)) of about 2.0 dB. Numerical results also show significant improvement in packet blocking probability by the proposed recursive PWC-based OPS in comparison with the previous non-recursive schemes.

Parallel WDM Signal Processing in Mixed NRZ and RZ Transmission Networks Using a Single Optical Gate With Multiple Switching Windows
Hung Nguyen Tan; Motoharu Matsuura; Naoto Kishi
IEEE JOURNAL OF SELECTED TOPICS IN QUANTUM ELECTRONICS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 18, 2, 926-934, Mar. 2012, Peer-reviwed, We propose and demonstrate in experiment a multiple switching-window optical gate (MW-OG) for applications on parallel multiwavelength processing. The proposed scheme is a multiwavelength compatible version of the conventional Sagnac interferometric switch that offers independent controllability of switching windows at different wavelengths. This feature makes possible the data format conversion from nonreturn-to-zero (NRZ) and return-to-zero (RZ) with parallel pulsewidth tunability for wavelength-division-multiplexed signals. It also leads to the multiwavelength regeneration against chromatic dispersion and amplified spontaneous emission noise for both NRZ and RZ signals over the optical sampling processes. The MW-OG is then used as inline signal regeneration in a mixed NRZ and RZ data format transmission network over standard single-mode fiber without dispersion compensation. The regeneration is carried out at a central node that works as a terminal and an intermediate for various interconnections among nodes. Transmission performances are significantly improved for all channels simultaneously by parallel pulsewidth management in accordance with their modulation formats and lightpaths.

Reconfigurable All-Optical OTDM-to-WDM Conversion Using a Multiwavelength Ultrashort Pulse Source Based on Raman Compression
Hung Nguyen Tan; Quang Nguyen-The; Motoharu Matsuura; Naoto Kishi
JOURNAL OF LIGHTWAVE TECHNOLOGY, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 30, 6, 853-863, Mar. 2012, Peer-reviwed, We propose and demonstrate a reconfigurable all-optical format conversion from optical time-division multiplexing (OTDM) to wavelength division multiplexing (WDM) providing full flexibility in terms of channel spacing and wavelength allocation. The system consists of a Raman amplification-based multiwavelength pulse compressor and a parametric sampling gate. Four conventionally generated WDM 10 GHz pulse trains are compressed at the same time to around 2.5 ps and, then, used for multiwavelength sampling of a 40 Gb/s 3.49 ps OTDM signal. Simultaneous extraction of all four 10 Gb/s tributaries to WDM channels in WDM grid with tunable channel spacing is demonstrated. Controlling time delays among the WDM clock channels makes it flexible to map OTDM tributaries onto any desired wavelength order, which is also called wavelength-and time-selective function. The reconfigurable functions can be realized independently on the coming OTDM signal by simply setting corresponding parameters of the WDM synchronous pulse trains at the terminals. This is also the key for the good overall performance obtained for all demultiplexed channels. Low power penalties below 1.9 and 2.1 dB are achieved with small penalty variations, 0.3 and 0.5 dB, among channels as the OTDM tributaries are converted to WDM grid with spacing of 400 and 200 GHz, respectively.

2012 IEEE 75TH VEHICULAR TECHNOLOGY CONFERENCE (VTC SPRING), IEEE, 10G-2, 2012, Peer-reviwed, Radio-over-Fiber (RoF) technology enables low-loss distribution of RF signals over optical fiber, which contributes much for spreading broadband wireless access services into in-building areas and outdoor dead-spots. However, current broadband wireless access systems employ OFDM schemes and suffer from nonlinear distortion of the RoF channel due to nonlinearity inherent in Electrical to Optical (E/O) conversion. In this paper, a new RoF transmission scheme employing Envelop Pulse-Width Modulation (EPWM) transmitter has been proposed to efficiently suppress the impact of RoF channel nonlinearity on OFDM signals. This idea is executed in a typical RoF channel that uses a Mach-Zehnder modulator as its E/O convertor. It is proved by both simulation and experiment that the EPWM-RoF scheme can achieve linear transmission of OFDM signal via nonlinear RoF channel.

2012 INTERNATIONAL CONFERENCE ON ADVANCED TECHNOLOGIES FOR COMMUNICATIONS (ATC 2012), IEEE, 349-352, 2012, Peer-reviwed, An optical time division multiplexing (OTDM) adddrop multiplexing using Raman amplification-based adiabatic soliton compressor (RA-ASC) and a fiber-based cross phase modulation (XPM) switch is experimentally demonstrated. A 10 Gb/s clock train is compressed by the RA-ASC and then acts as a control signal in the fiber-based XPM switch to perform the OTDM add-drop multiplexing. A 10 Gb/s data channel is dropped from a 40 Gb/s OTDM data signal and a new 10 Gb/s data channel is added in its place. Below 2-dB power penalties are obtained for all demultiplexed channels after OTDM add-drop multiplexing.

2012 INTERNATIONAL CONFERENCE ON ADVANCED TECHNOLOGIES FOR COMMUNICATIONS (ATC 2012), IEEE, 353-356, 2012, Peer-reviwed, We propose the use of cross-gain modulation (XGM) for multichannel NRZ-to-RZ data format conversion in a single semiconductor optical amplifier (SOA). Four 10Gb/s WDM NRZ signals are converted simultaneously to RZ format without logic inversion. The proposed technique is advantageous over previous schemes due to its particular simplicity, polarization independency, and wavelength-shift-free operation. It maintains good performance under 16.5dB input power dynamic range, and large time and wavelength offsets between input signals and control clock.

All-Optical NRZ-to-RZ Data Format Conversion with Picosecond Duration-Tunable and Pedestal Suppressed Operations
Quang Nguyen-The; Motoharu Matsuura; Hung Nguyen Tan; Naoto Kishi
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E94C, 7, 1160-1166, Jul. 2011, Peer-reviwed, We demonstrate an all-optical picosecond pulse duration-tunable nonreturn-to-zero (NRZ)-to-return-to-zero (RZ) data format conversion using a Raman amplifier-based compressor and a fiber-based four-wave mixing (FWM) switch. A NRZ data signal is injected into the fiber-based FWM switch (AND gate) with a compressed RZ clock by the Raman amplifier-based compressor, and convert to RZ data signal by the fiber-based FWM switch. The compressed RZ clock train acts as a pump signal in the fiber-based FWM switch to perform the NRZ-to-RZ data format conversion. By changing the Raman pump power of the Raman amplifier-based compressor, it is possible to tune the pulse duration of the converted RZ data signal from 15 ps to 2 Ps. In all the tuning range, the receiver sensitivity at bit error rate (HER) of 10(-9) for the converted RZ data signal was about 1.3 similar to 1.7 dB better than the receiver sensitivity of the input NRZ data signal. Moreover, the pulse pedestal of the converted RZ data signals is well suppressed owing to the FWM process in the fiber-based FWM switch.

Recursive Parametric Wavelength Conversion Scheme for Optical Packet Switch
Nattapong Kitsuwan; Hung Nguyen Tan; Motoharu Matsuura; Naoto Kishi; Eiji Oki
JOURNAL OF LIGHTWAVE TECHNOLOGY, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 29, 11, 1659-1670, Jun. 2011, Peer-reviwed, This paper proposes a scheme to increase possible patterns of wavelength-conversion for an optical packet switch (OPS) with parametric wavelength converters (PWCs) by obtaining additional converted wavelengths using the existing resources. It is called a recursive parametric wavelength conversion (RPWC) scheme. A PWC uses a pump wavelength to define the original and converted wavelengths, called wavelength conversion pairs. None of conversion pairs from any PWCs can sometime support the request, although some wavelengths at the requested output fiber are available. Therefore, packet loss occurs and several conversion pairs are wasteful. In RPWC, unused conversion pairs are used to create additional conversion pairs. The OPS allows each wavelength to be converted using combination of unused conversion pairs using more than one PWC, instead of using only a single PWC as in a conventional scheme. Simulation results show that RPWC achieves lower packet loss rate than the conventional scheme, under both uniform and non-uniform traffic. To show the feasibility of RPWC, we develop a prototype of an optical switch with RPWC and demonstrate it in experiment.

Wavelength Assignment in Multi-Carrier Distributed Optical Ring Networks With Wavelength Reuse
Masafumi Keri; Eiji Oki; Motoharu Matsuura
JOURNAL OF OPTICAL COMMUNICATIONS AND NETWORKING, OPTICAL SOC AMER, 3, 4, 281-289, Apr. 2011, Peer-reviwed, This paper investigates the problem of wavelength assignment in wavelength reusable multi-carrier distributed (WRMD) wavelength-division-multiplexing (WDM) ring networks. In conventional WDM ring networks, each edge node (EN) has its own light sources, and optical channels, called lightpaths, are established by using optical carriers generated from laser diodes (LDs) at the source EN. However, such networks will suffer from the need for complicated wavelength management (e. g., monitoring LDs, avoiding wavelength collision) in the future since each EN requires a large number of LDs to deal with the exponential increase in traffic. On the other hand, a WRMD ring network overcomes this problem. In this network, lightpaths between source and destination ENs are established by using carriers generated from a centralized multi-carrier light source. Moreover, the carrier regeneration technique is applied for the purpose of reducing the number of wavelengths used for lightpath establishment. Although optical carrier regeneration reduces the number of wavelengths, the quality of the regenerated carrier is slightly degraded after carrier regeneration. Therefore, in the WRMD network, the allowable number of carrier regenerations per wavelength must be limited in order to avoid communication error. This paper formulates the wavelength assignment problem, minimizing the number of wavelengths needed to establish all requested lightpaths, as the vertex coloring problem, and then an integer linear programming (ILP) solution is provided. Since ILP problems are non-deterministic polynomial-time( NP-) complete, a heuristic algorithm is developed. Numerical results indicate that our developed algorithm performs well in our test cases. It is observed that one and two carrier regenerations per wavelength reduce the number of wavelengths for lightpath establishment by approximately 50% and 60%, respectively, compared to that without carrier regeneration. The results also show that regenerating carriers more than two times per wavelength has little effect on the required number of wavelengths regardless of the number of ENs.

Enhancement of Input Power Dynamic Range for Multiwavelength Amplification and Optical Signal Processing in a Semiconductor Optical Amplifier Using Holding Beam Effect
Hung Nguyen Tan; Motoharu Matsuura; Naoto Kishi
JOURNAL OF LIGHTWAVE TECHNOLOGY, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 28, 17, 2593-2602, Sep. 2010, Peer-reviwed, We demonstrate a considerable enhancement of input power dynamic range (IPDR) for multiwavelength amplification and optical signal processing in a semiconductor optical amplifier (SOA) by using holding beam effect. The effect is used in SOA gain region at power level well below 10 dBm, which is much smaller than the required power as the setting at transparency wavelength. The IPDR is extended not only to high power range due to the reduction of nonlinear crosstalks, but also to low power range due to the compression of amplified spontaneous emission (ASE) noise. The technique is first applied to the amplification of wavelength-division multiplexed (WDM) channels using a continuous wave (CW) holding beam. The holding beam is particularly useful for the amplification of large number of channels thanks to the suppression effect of interactions among WDM channels. It is then carried out for one of extensively-used optical processing schemes, terahertz optical asymmetric demultiplexer (TOAD), for multiwavelength data format conversion without the need of an external CW light. The IPDR of TOAD reaches over 20 dB as control clock behaves simultaneously as the holding beam. We also present that the patterning effect and the impact of ASE noise on the converted signal are strongly dependent on the TOAD's switching window, which is optimized at 40% duty ratio for the largest IPDR.

Performance of Optical Packet Switches Based on Parametric Wavelength Converters
Nattapong Kitsuwan; Roberto Rojas-Cessa; Motoharu Matsuura; Eiji Oki
JOURNAL OF OPTICAL COMMUNICATIONS AND NETWORKING, OPTICAL SOC AMER, 2, 8, 558-569, Aug. 2010, Peer-reviwed, In an optical packet switch (OPS), input fibers carry multiple wavelengths, each of which carries a packet to one output fiber. As several wavelengths from different inputs could be destined to the same output fiber, one wavelength can be connected and the others remain disconnected, losing the carried packets. Because of the multiple wavelengths available at an output fiber, wavelength conversion in the OPS of the unconnected wavelengths into those available can increase the number of connections. A parametric wavelength converter (PWC) provides multichannel wavelength conversion where wavelengths can be converted to another. A PWC uses a pump wavelength that can be flexibly chosen to define which wavelengths can be converted, defining the so-called wavelength conversion pairs. However, it is unknown which set of pump wavelengths, and therefore the set of connection pairs, should be selected to improve the OPS performance while the number of PWCs in the OPS is reduced. This paper proposes a pump wavelength selection policy for an OPS that uses different pump wavelengths, one for each PWC, within an arbitrarily selected interval. This policy is called a variety-rich (VR) policy. This paper also introduces a non-wavelength-blocking OPS (NWB-OPS) to make full use of PWCs. The switch performance is evaluated through computer simulation. The results show that the proposed policy with different pump wavelengths achieves the highest performance when compared with another of similar complexity. Furthermore, the performance study shows that small sizes of the interval to select a pump wavelength are more beneficial than larger ones.

Multi-carrier distributed WDM ring network based on reconfigurable optical drop-add-drop multiplexers and carrier wavelength reuse
Motoharu Matsuura; Eiji Oki
IEEE International Conference on Communications, 2010, Peer-reviwed, This paper presents and experimentally demonstrates a multi-carrier distributed wavelength-division-multiplexing (WDM) ring network based on reconfigurable optical "drop-add-drop" multiplexers for regional and metro network applications. In the "drop-add-drop" network, optical carriers generated by a centralized multi-carrier light source (MCLS) are "dropped" at the source nodes and used for uplink transmission. Data are "added" to the network by external modulation of one or more carriers. Data are then "dropped" at the destination nodes. The reconfigurable optical add/drop multiplexer (ROADM) at each access node is not only used to "add" and "drop" data, but also to "drop" carriers, which eliminates the many distributed laser-diodes used in the conventional network. In this work, we successfully demonstrate, for the first time, a "drop-add-drop" network experiment offering 10 Gbit/s WDM transmission. Moreover, to dramatically improve the utilization efficiency of the carrier wavelengths distributed by the MCLS in the "drop-add-drop" network, we introduce the carrier wavelength reuse technique which sets the carrier extraction circuits in each access node. This technique enables us to reuse the carrier wavelengths that were already utilized for data transmission between prior source and destination nodes. To evaluate the effect of carrier wavelength reuse, we compare the blocking probabilities of the "drop-add-drop" networks with and without carrier wavelength reuse. The results show that wavelength reuse dramatically reduced the blocking probability. In addition, we numerically analyze the advantages of the "drop-add-drop" network over the conventional ROADM network in terms of network cost and power consumption. ©2010 IEEE.

Resilient Optical Broadcast-and-Select Network Using Centralized Multi-Carrier Light Source
Yueping Cai; Motoharu Matsuura; Eiji Oki; Naoto Kishi; Tetsuya Miki
2010 14TH CONFERENCE ON OPTICAL NETWORK DESIGN AND MODELING (ONDM), IEEE, P-4, 2010, Peer-reviwed, This paper presents a resilient star-ring optical broadcast-and-select network with a centralized multi-carrier light source (C-MCLS). It consists of a star part network and a ring part network. Optical carriers generated by the C-MCLS are broadcast to all network nodes, which select and utilize them for data transmission. Optical carrier distribution and data transmission are performed in the star part network. The ring part network is for fiber failure recovery. The network resilience property enables the design of a fast distributed failure recovery scheme to deal with single and multiple fiber failures. We introduce a fiber connection automatic protection switching (FC-APS) architecture that only consists of optical couplers and switches for each network node. We design a distributed failure recovery scheme based on it. The fiber failure detection and failure recovery operations are performed by each network node independently only using its local information. We evaluate the recovery time of the distributed scheme compared with that of the centralized one. Numerical results show that it greatly reduces the recovery time than the centralized one.

Performance of an Optical Packet Switch with Parametric Wavelength Converters
Nattapong Kitsuwan; Roberto Rojas-Cessa; Motoharu Matsuura; Eiji Oki
2010 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS, IEEE, ON03-3, 2010, Peer-reviwed, In an optical packet switch (OPS), input fibers carry multiple wavelengths, which carry packets to one or more output fibers. As several wavelengths from different inputs could be destined to the same output fiber, one wavelength can be connected and the others remain disconnected, losing the carried packets. Because of the multiple wavelengths available at an output fiber, wavelength conversion in the OPS of the unconnected wavelengths into those available can increase the number of connections. A parametric wavelength converter (PWC) provides multi-channel wavelength conversion where wavelengths can be converted to another. A PWC uses a pump wavelength that can be flexibly chosen to define which wavelengths can be converted, defining the so-called wavelength conversion pairs. However, it is unknown which set of pump wavelengths, and therefore the set of connection pairs, should be selected to improve the OPS performance while minimizing the number of PWCs in the OPS. Therefore, this paper proposes a pump wavelength selection policy for an OPS that uses different pump wavelengths, one for each PWC, within an arbitrarily selected interval. This policy is called variety rich (VR) policy. This paper also introduces a non-wavelength blocking OPS (NWB-OPS) to make full use of PWCs. The switch performance is evaluated through computer simulation. The results show that the proposed policy with different pump wavelengths achieves the highest performance when compared to another of similar complexity. Furthermore, the performance study shows that small sizes of the interval to select a pump wavelength are more beneficial than larger ones.

Multi-Carrier Distributed WDM Ring Network Based on Reconfigurable Optical Drop-Add-Drop Multiplexers and Carrier Wavelength Reuse
Motoharu Matsuura; Eiji Oki
2010 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS, IEEE, ON03-4, 2010, Peer-reviwed, This paper presents and experimentally demonstrates a multi-carrier distributed wavelength-division-multiplexing (WDM) ring network based on reconfigurable optical "drop-add-drop" multiplexers for regional and metro network applications. In the "drop-add-drop" network, optical carriers generated by a centralized multi-carrier light source (MCLS) are "dropped" at the source nodes and used for uplink transmission. Data are "added" to the network by external modulation of one or more carriers. Data are then "dropped" at the destination nodes. The reconfigurable optical add/drop multiplexer (ROADM) at each access node is not only used to "add" and "drop" data, but also to "drop" carriers, which eliminates the many distributed laser-diodes used in the conventional network. In this work, we successfully demonstrate, for the first time, a "drop-add-drop" network experiment offering 10 Gbit/s WDM transmission. Moreover, to dramatically improve the utilization efficiency of the carrier wavelengths distributed by the MCLS in the "drop-add-drop" network, we introduce the carrier wavelength reuse technique which sets the carrier extraction circuits in each access node. This technique enables us to reuse the carrier wavelengths that were already utilized for data transmission between prior source and destination nodes. To evaluate the effect of carrier wavelength reuse, we compare the blocking probabilities of the "drop-add-drop" networks with and without carrier wavelength reuse. The results show that wavelength reuse dramatically reduced the blocking probability. In addition, we numerically analyze the advantages of the "drop-add-drop" network over the conventional ROADM network in terms of network cost and power consumption.

Multiple-channel optical signal processing with wavelength-waveform conversions, pulsewidth tunability, and signal regeneration
Hung Nguyen Tan; Motoharu Matsuura; Tomoya Katafuchi; Naoto Kishi
OPTICS EXPRESS, OPTICAL SOC AMER, 17, 25, 22960-22973, Dec. 2009, Peer-reviwed, A multiple-channel multiple-function optical signal processor (MCMF-OSP) including wavelength-waveform conversions, pulsewidth tunability, and signal regeneration is realized through AND logic gate based on optical parametric processing with a pulsewidth-tunable RZ clock pump. The proposed scheme simultaneously offers four signal processing functions which are useful in wavelength-division multiplexing (WDM) transmission systems, and at network nodes with the necessity for multiple-channel data processing. After the discussions on the concept of MCMF-OSP, a proof-of concept experiment is demonstrated on four 10 Gb/s nonreturn-to-zero (NRZ) data format channels using nonlinearities in semiconductor optical amplifier (SOA) and highly nonlinear fiber (HNLF). A wavelength and waveform conversions to return-to-zero (RZ) modulation format are obtained together with pulsewidth-tunable range from 20% to 80% duty cycles for all input signals. The converted signals inherit the timing and waveform of the RZ clock pump, thus resulting in a time regeneration and large tolerance to narrow-band optical filtering (NAOF) and fiber accumulated chromatic dispersion (CD).

Design and Evaluation of an Optical Broadcast-and-Select Network Architecture With a Centralized Multicarrier Light Source
Yueping Cai; Eiji Oki; Motoharu Matsuura; Naoto Kishi; Tetsuya Miki
JOURNAL OF LIGHTWAVE TECHNOLOGY, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 27, 21, 4897-4906, Nov. 2009, Peer-reviwed, This paper presents the design and evaluation of our optical broadcast-and-select wavelength-routed network architecture that uses a centralized multicarrier light source (C-MCLS). The large number of optical carriers/wavelengths generated by the C-MCLS are distributed to all edge nodes (ENs), which select and modulate wavelengths to realize upstream transmission. To utilize wavelengths efficiently, we introduce a framework for wavelength allocation and selection (WAS). Both static and dynamic schemes are adopted for WAS and their implementations are shown. By using fixed or tunable band pass filters and periodic arrayed waveguide grating demultiplexers, wavelengths are selected and utilized by ENs in a static or dynamic manner. After considering the design parameters used in the implementations, wavelength allocation procedures are described. We evaluate the cost, power consumption and network performance of the proposed network. Numerical results show that it offers greatly reduced cost and power consumption compared to the conventional one when the number of required access wavelengths at EN becomes large. We delineate its applicable areas through cost comparisons. Blocking probabilities of static and dynamic schemes are analyzed to evaluate network performance. Numerical results show that by choosing appropriate design parameters, the dynamic scheme offers about 25% increase in admissible offered load under the specified blocking probability, compared to the static scheme. This indicates that the dynamic scheme makes the proposed network more robust against traffic fluctuations.

IEEE COMMUNICATIONS LETTERS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 13, 9, 700-702, Sep. 2009, Peer-reviwed, This letter proposes an optical drop-add-drop network architecture with a centralized multi-carrier light source (C-MCLS) for regional and metro network applications., In the drop-add-drop network, optical carriers generated by the G MCLS are dropped at the source nodes and used for uplink transmission. Data are added to the network after external modulations of the carriers. Data are then dropped at the destination nodes. The reconfigurable optical add/drop multiplexer (ROADM) at each node is not only used to add and drop data, but also to drop carriers, which eliminates the distributed laser diodes needed by the conventional network. Network cost analysis and numerical results show that it offers significantly lower network cost compared to the conventional network if the total number of used wavelengths in the network is large. We evaluate its optical performance through an optical signal-to-noise ratio (OSNR) analysis. We show its applicable network size in terms of fiber span length and the number of nodes under a specified bit error rate (BER) when changing the OSNR of the C-MCLS.

OPTICS EXPRESS, OPTICAL SOC AMER, 16, 23, 19063-19071, Nov. 2008, Peer-reviwed, An all-optical signal processing scheme coupling wavelength conversion and NRZ-to-RZ data format conversion with pulsewidth tunability into one by combination of SOA- and fiber-based switches, is experimentally demonstrated, and its transmission performance is investigated. An 1558 nm NRZ data signal is converted to RZ data format at 1546 nm with widely tunable pulsewidth from 20 % to 80 % duty cycle at the bit-rate of 10 Gb/s.

The results clarify a significant improvement on transmission performance of converted signal in comparison with the conventional NRZ signal through tunable pulsewidth management and show the existence of an optimal pulsewidth for the RZ data format at each transmission distance with particular cumulative dispersion. The optimal pulsewidths of the converted RZ signal and its corresponding power penalties against the NRZ signal are also investigated in different SSMF links. (C) 2008 Optical Society of America

2008 14TH ASIA-PACIFIC CONFERENCE ON COMMUNICATIONS, (APCC), VOLS 1 AND 2, IEEE, 387-391, 2008, Peer-reviwed, This paper presents a survivable optical broadcast-and-select network architecture with centralized multi-carrier light source for regional or metro-core network applications. A large number of optical carriers generated by the single multi-carrier light source are shared and utilized by all edge nodes of the regional network through dynamic wavelength/waveband broadcast and select. The design of this network architecture aims to reduce network cost and increase network survivability. Combined with optical couplers and 1 x 2 optical switches based protection architecture, the proposed network enables a fast failure-recovery scheme design. It recovers the network from different fiber cut failures in a fast and cost-effective way. The recovery time analysis and calculations under different situations are carried out to evaluate the performance of the proposed failure-recovery scheme. Results show that the recovery time is largely impacted by the switching time of 1 x 2 optical switches and it is small enough to meet the standard 50 ms requirements with 1 ms switches.

OPTICS EXPRESS, OPTICAL SOC AMER, 15, 25, 16316-16321, Dec. 2007, Peer-reviwed, We investigate discrete wavelength tuning characteristics of a single-frequency fiber laser locked to either of two external lights. Frequency locking is achieved by the cooperatively induced spatial-hole burning (SHB) of a saturable absorber in the laser cavity. We show that lasing frequency is well locked to either of the two external lights when the lasing wavelength of the fiber laser is adjusted to the corresponding wavelength of the external light by tuning the bandpass filter in the laser cavity. The locked frequency stability of the fiber laser is as high as that of the employed external light source. (c) 2007 Optical Society of America.

Ultrawideband wavelength conversion using cascaded SOA-based wavelength converters
Motoharu Matsuura; Naoto Kishi; Tetsuya Miki
Lead, IEEE/OSA Journal of Lightwave Tecnology, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 25, 1, 38-45, Jan. 2007, Peer-reviwed, Invited, An all-optical wavelength converter with a large wavelength hopping range is proposed and demonstrated. This converter consists of multistage cascaded wavelength converters using semiconductor optical amplifiers each with different gain band. Each of the cascaded wavelength converters enables us to perform both noninverted (NIV) and inverted (IV) operations. Conversion performance is compared at NIV and IV operations in terms of static characteristics as a function of input/output power of the converter. While good conversion performances are achieved at both operations, the IV wavelength conversion has better cascadability to obtain a high-quality converted signal for the cascaded scheme. Moreover, signal amplitude regeneration is demonstrated by repeating the IV wavelength conversion. Finally, we successfully demonstrate, for the first time, ultrawideband wavelength conversion, including over 300-nm wavelength hopping to the shorter wavelength side with a triple-stage cascaded wavelength converter.

Hybrid static-dynamic wavelength/waveband allocation scheme for novel broadcast and select star-ring optical regional network
Yueping Cai; Motoharu Matsuura; Naoto Kishi; Tetsuya Miki
2007 ASIA-PACIFIC CONFERENCE ON COMMUNICATIONS, IEEE, 513-516, 2007, Peer-reviwed, We have proposed a novel star-ring optical regional network architecture with dynamic wavelength/waveband broadcast and select based on bandwidth reservation. In this network, the large number of wavelength resources generated by a single multi-carrier light source can be shared and utilized in a flexible and simple way. In this paper, a hybrid static-dynamic wavelength/waveband allocation scheme combined with dynamic traffic banding has been proposed to reduce the network cost and complexity. To achieve this goal, we define one hybrid static-dynamic wavelength/waveband partition scheme, and develop two wavelength/waveband allocation algorithms based on it. One is Maximum Waveband First (MWF) allocation and the other is Waveband Round Robin (WRR) allocation. Both physical implementation analysis and computer simulation have been carried out to verify our ideas. According to the results, our proposal can effectively reduce the number of used optical switching ports and simplify the edge node architecture.

IWASAKI Wataru; MATSUURA Motoharu; KISHI Naoto

Pulsewidth Tunable and Polarization-Insensitive NRZ-to-RZ Conversion by Using Fiber Nonlinearity Based Circuits
MOHAMMADSHARIF Gazi; NGUYEN-THE Quang; MATSUURA Motoharu; KISHI Naoto
We demonstrate a polarization-insensitive non-return-to-zero (NRZ) to pulsewidth tunable return-to-zero (RZ) conversion based on a fiber based NRZ-to-RZ converter which consists a polarization diversity loop and a Raman amplifier (RA)-based pulse compressor. In our scheme, polarization insensitive operation is achieved due to the polarization diversity loop with a polarization beam splitter (PBS) inside this loop. The signals enter the PBS and propagate both of the directions inside the loop before entering the highly nonlinear fiber (HNLF). Moreover, by changing the Raman pump power of the RA-based pulse compressor in this scheme, the pulsewidth of the converted RZ signal can be flexibly tuned from 10ps to 2ps., The Institute of Electronics, Information and Communication Engineers, 18 Oct. 2012, Technical report of IEICE.

Performance of Optical Packet Switch based on Recursive Parametric Wavelength Conversions
KITSUWAN Nattapong; NGUYEN TAN Hung; MATSUURA Motoharu; KISHI Naoto; OKI Eiji
This paper presents performances of a scheme that increase possibility to convert wavelengths using the existing resources in an optical packet switch (OPS) with parametric wavelength converters (PWCs). It is called a recursive parametric wavelength conversion (RPWC). A pump wavelength is used to define the original and converted wavelengths, called wavelength conversion pairs, in a PWC. Although wavelengths at the requested output fiber are available, none of PWCs can support the requests. Some packet losses may occur. Several conversion pairs are, sometime, wasteful since they are not utilized. In RPWC, unused conversion pairs are used to create additional conversion pairs. The OPS allows each wavelength to be converted using combination of unused conversion pairs using more than one PWCs, instead of using only a single PWC as in a conventional scheme. Numerical results via simulation show that RPWC achieves lower packet loss rate than the conventional scheme., The Institute of Electronics, Information and Communication Engineers, 07 Nov. 2011, 電子情報通信学会技術研究報告 : 信学技報, 111, 274, 51-55, English, 0913-5685, 110009465535, AA11864040

Wavelength Assignment in a Wavelength Reusable Network Considering Wavelength Regenerations
KERI Masafumi; OKI Eiji; MATSUURA Motoharu
This paper proposes a wavelength assignment algorithm that minimizes the number of wavelengths used in a wavelength reusable WDM network. Wavelength utilization is improved by applying optical carrier regeneration techniques that allow multiple use of wavelengths, while the number of carrier regenerations should be considered since the optical signal to noise ratio (OSNR) of the regenerated carrier is degraded after carrier regeneration, resulting in worse communication quality. The numerical results show that two optical carrier regenerations per wavelength reduces the number of wavelengths for lightpath establishment by more than 60%, compared to that without carrier regeneration., The Institute of Electronics, Information and Communication Engineers, 21 Feb. 2011, IEICE technical report, 110, 431, 29-32, Japanese, 0913-5685, 110008688501, AA11864040

An Optical Packet Switch based on Parametric Wavelength Converters
KITSUWAN Nattapong; ROJAS-CESSA Roberto; MATSUURA Motoharu; OKI Eiji
In an optical packet switch (OPS), input fibers carry multiple wavelengths, which carry packets to one or more putput fibers. As several wavelengths from different inputs could be destined to the same output fiber, one wavelength can be connected and the others remain disconnected, losing the carried packtes. Becase of the multiple wavelengths available at an output fiber, wavelength conversion in the OPS of the unconnected wavelengths into those available can increase the number of connections. A parametric wavelength converter (PWC) provides multi-channel wavelength conversion where wavelengths can be converted to another. A PWC uses a pump wavelength that can be flexibly chosen to define which wavelengths can be converted, defining the so-called wavelength conversion pairs. However, it is unknown which set of pump wavelengths, and therefore the set of connection pairs, should be selected to improve the OPS performance while minimizing the number of PWCs in the OPS. Therefore, this paper proposes a pump wavelength selection policy for an OPS that uses different pump wavelengths, one for each PWC, within an arbitrarily selected interval. This policy is called variety rich (VR) policy. This paper also introduces a non-wavelength blocking OPS (NWB-OPS) to make full use of PWCs. The switch performance is evaluated through computer simulation. The results show that the proposed policy with different pump wavelengths achieves the highest performance when compared to another of similar complexity. Furthermore, the performance study shows that small sizes of the interval to selecta pump wavelength are more benefical than larger ones., The Institute of Electronics, Information and Communication Engineers, 01 Mar. 2010, IEICE technical report, 109, 455, 31-36, English, 0913-5685, 110007999530, AA11864040

Studies for regenerative conversion functions for several format signals in mixed-format optical communication systems
Kishi Naoto; Matsuura Motoharu; Quang Nguyen-The; Irneza Ismail; Nguyen Quang Nhu Quynh; Shimazaki Kouhei; Yokota Ryou; Kobayshi Tatsuya; Asano Kouya; Zhang Yingy; Matsumoto Hiroki
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (C), There are different signal formats in optical fiber communication networks. In such networks, processing function in network node should work independently from the signal formats, such as intensity- and phase-modulations. In this project, regenerative optical signal processing functions, such as pulsewidth tunable regenerative pulsewidth conversion, optical multicasting function to distribute a single-channel signal to multiple-wavelength channels, conversion of a wavelength-division multiplexing signal to a optical time-division multiplexing signal, and distortion-compensating variable optical delay line to change the timing of the signal, are studied. These processing functions are investigated for phase-modulated signal as well as conventional intensity-modulated signals. The results of the study suggest that most of these functions are applicable independent from the signal formats., 15K06056

KISHI Naoto; MATSUURA Motoharu
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B), In optical communication networks, optical node functions are very important which convert the signal wavelength and waveform and/or compensate signal distortions. So far, such optical node functions have assumed the same signal format. On the other hand, there are many signal formats according to the properties of the signal sources and destinations. In this study, optical node functions which allow multiple signal formats were investigated. The research results include realization of (1) wavelength/waveform conversion and waveform reshaping function applicable to various signal modulation formats, (2) polarization- and signal format-independent waveform conversion function, and (3) OTDM(optical time-division multiplexing) to WDM(wavelength-division multiplexing) conversion function., 24360148

KISHI Naoto; MATSUURA Motoharu
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (C), Variable optical delay-line is very important for optical signal timing adjustment in optical communication networks. In this study, optical Fourier transformation(OFT) is appliedto such variable optical delay-line to realize distortion-free operation. The characteristics of the OFTincorporatedoptical delay-line, which is realized with a phase modulator, a suitable length of opticalfiber, and a wavelength converter is evaluated. Distortion-free as well as variable time-delay operation of the delay-line is successfully demonstrated., 21560350
