Abstract

InGaAsP/InP buffer-layer loaded planoconvex waveguide lasers are reported. The cw threshold current at 20 degree C was 70 ma. A maximum cw operating temperature of 70 degree C was achieved. The characteristic temperature under cw operation was 51 K. Operation in fundamental transverse mode and single longitudinal mode up to 1. 9 and 1. 4 times the threshold current, respectively, was obtained.
