Abstract (in Japanese) (See Japanese page) 
(in English) Silicon photonics optical source that is compatible with CMOS electronics is a prerequisite component for realizing high-speed optical interconnect. In this work, we developed the hybrid laser source consisting of a silicon-wire external cavity filter and a semiconductor optical amplifier (SOA). The silicon-wire external cavity filter is composed of an optical coupler, a microring resonator (MRR) and a Bragg reflector, and the oscillation wavelength is determined by the MRR. To realize a highly efficient optical transmitter without using any thermal tuning architecture, we investigated the synchronization of the operating ranges of the laser source and the MRR-type optical modulator with respect to temperature change by placing the same sized MRR as that used in the MRR-type optical modulator in the laser cavity. We fabricated the silicon-wire external cavity filter, and experimentally evaluated the laser oscillation characteristics by optically connecting the SOA to the fabricated filter. As a result, clear laser oscillation spectra were observed. Additionally, the temperature dependent wavelength shift for the silicon external cavity laser (0.077 nm/oC) was comparable to that of the MRR-based optical modulator (0.073 nm/oC). This justifies that the proposed transmitter does not need any thermal tuning architecture for synchronizing the operating ranges for the laser and the optical modulator, thus enabling to realize compact and power efficient optical transmitter.
