Paper Abstract

To our knowledge, this is the first report of a monolithically integrated distributed feedback (DFB) semiconductor laser array based on reconstruction-equivalent-chirp (REC) technology. A laser bar with 30 different lasers is obtained, lasing at 30 different wavelengths under single longitudinal mode. The typical threshold is about 40mA to 60mA. The typical slope efficiency is about 0.07 mW/mA to .13 mW/mA. Tested under the injection current of 100mA, the side mode suppression ratios (SMSR) range from 24.9dB to 46.8 dB, with an average of 37.2dB. The proposed method is presented in hoping to make a positive contribution to large-scale photonics integrated circuits (PIC) research for the nextgeneration fiber-optic networks.
