MOC 2019 - 24th Microoptics Conference, Institute of Electrical and Electronics Engineers Inc., 308-309, 01 Nov. 2019, We report local wavelength tuning of quantum-dot single-photon sources integrated on a CMOS silicon chip as well as in-situ spectral matching between two dissimilar sources. All the necessary heterogeneous integration processes were performed in a simple pick-and-place manner based on transfer printing, largely facilitating the fabrication of complicated device structures.

APPLIED PHYSICS LETTERS, AMER INST PHYSICS, 107, 7, Aug. 2015, Peer-reviwed, We experimentally demonstrate a three-dimensional photonic crystal (3D PC) nanocavity in a < 110 >-layered diamond structure with a quality factor (Q-factor) of 12 800 at a wavelength of 1.1 mu m. The observed Q is 1.2 times higher than that of a 3D PC nanocavity in a woodpile structure with the same in-plane size and the same number of stacked layers. This result indicates the potential importance of the < 110 >-layered diamond structure for getting high Q 3D PC nanocavities within a limited in-plane space. (C) 2015 AIP Publishing LLC.
