Abstract
0.98 mu m-emitting, broad-waveguide-type InGaAs/InGaP/GaAs diode laser s have been optimised for maximum wallplug efficiency. Optimised-facet -coated, 100 mu m-widestripe, 500 mu m-long devices having InGaAsP opt ical-waveguide thicknesses of 0.6 and 1.2 mu m provide maximum wallplu g efficiencies of 66% and 62%, respectively. Carbon-doped cap layers a llow for a series resistance of 0.08 Ohm for devices with 100 X 500 mu m(2) contact area.
