Abstract
A simple method for fabricating gain coupled DFB lasers with lateral surfac e chromium Bragg gratings and self-aligned low capacitance ohmic contacts i s reported. These InGaAsp/InP lasers show monomode emission with a sidemode suppression ratio of 40dB. For 243 mu m long devices a continuous wave thr eshold current of 17mA was measured at room temperature.
