摘要

This paper reports that the complex-coupled distributed feedback laser with the sampled grating has been designed and fabricated. The +lst order reflection of the sampled grating is utilized for laser single mode operation, which is 1.5387 μm in the experiment. The typical threshold current of the device is 30 mA, and the optical output power is about 10 mW at the injection current of 100 mA.
