Abstract

An index-coupled distributed feedback laser with the sampled grating has been designed and fabricated. The +1^st order reflection of the sampled grating is utilized for laser single mode operation, which is 1.5329 mum in the experiment. The sampled grating is formed by a conventional holographic exposure combined with the usual photolithography. The typical threshold current of DFB laser with the sampled grating is 25 mA, and the optical output is about 10 mW at the injected current of 100 mA.
