Abstract

Room temperature cw operation of distributed-feedback buried-heterostructure InGaAsP/InP lasers emitting at 1. 57 mu m was achieved. A dc threshold of about 250 ma at 25 degree C and a temperature coefficient of the lasing wavelength of 1. 0 A/ degree C were obtained. Some of these lasers manifested single longitudinal mode operation both in dc condition and in deeply modulated condition at 500 Mbit/s.
