The threshold current I//t//h of a 1. 5 mu m range InGaAsP/InP lambda /4-shifted DFB laser with low-reflectivity ends was theoretically expected to be 10 ma or less. Experimentally, I//t//h of 14-16 ma at 20 degree C and the sub-mode suppression ratio of about 35 db or more in the temperature range of 10-70 degree C were obtained.
