Abstract

A monolithic integrated injection-locked distributed feedback laser based on reconstruction equivalent chirp technique is proposed. It is proved that the optical injection-locked enhances the quality of optical frequency comb, which can realize the wide range adjustment of different comb spacing within 2GHz-10GHz. The 10-db spectral width of the OFC with different comb spacing is between 66-119GHz. CNR up to 45dB.
