Abstract
The room temperature, continuous-wave (CW) operation of a fabricated multi- diode cascade vertical-cavity surface-emitting laser at 980nm wavelength, w ith a differential quantum efficiency exceeding unity, is demonstrated for the first time. A maximum wallplug efficiency of 16% is obtained at a drivi ng current of three limes the threshold.
