  • Abstract
    0.98 μm-emitting, broad-waveguide-type InGaAs/InGaP/GaAs diode lasers have been optimised for maximum wallplug efficiency. Optimised-face-coated, 100 μm-widestripe, 500 μm-long devices having InGaAsP optical-waveguide thicknesses of 0.6 and 1.2 μm provide maximum wallplug efficiencies of 66% and 62%, respectively. Carbon-doped cap layers allow for a series resistance of 0.08 Ω for devices with 100×500 μm2 contact area
