摘要

The slope efficiency (ηs) and the output power (Pout) of proton-implant-isolated AlGaAs/GaAs vertical-cavitysurface-emitting lasers (VCSELs) improve dramatically as the temperatureis decreased, with ηss≈20% at room temperature. This suggests that the VCSELcan be a very efficient device for cryogenic applications. In this paperwe report the first VCSEL that has been optimized for operation near 77K, with characteristics that are superior to those of VCSELs operatingat room temperature, including high output power (Pout=22mW), high power conversion efficiency (ηd=32%), highslope efficiency (ηs=75%-95%), low threshold voltage (Vth=1.75 V) and current (Ith=2 mA), and low powerdissipation (Pd<10 mW for Pout=2.5 mW) for a 20μm diameter device
