Abstract (in Japanese) (See Japanese page) 
(in English) We report on the development of a single wavelength laser module to meet the challenges of low cost and low power consumption for short reach application of gray link coherent communication system. A light source module for coherent communications requires two functions of a light source and a wavelength locker. Because conventional wavelength lockers have complex configurations, we have proposed an one-chip wavelength locker based on Si photonics technology and verified its operation so far. In this paper, we fabricated the first light source module that integrates a DFB laser and an one-chip wavelength locker in a TO-CAN package, based on our previous works. The light source module exhibited wavelength dependence as designed, and the evaluation of frequency stability by thermistor control and wavelength locker control showed that the wavelength locker control showed a low case temperature dependence of -0.03 GHz/K, about 1/6 that of the thermistor control. The result shows that ± 1.1 GHz can be obtained in the temperature range specified in the OIF standard, and a high frequency stability applicable to digital coherent communications has been successfully realized.
