A lower energy barrier p-type Al0.67Ga0.33As-GaAs DBR mirror has been incorporated into a previously reported vertical-cavity surface-emitting laser structure. CW measurements at room temperature demonstrate lower threshold voltages of 1.86 V, and a record high power-conversion efficiency of 14.9% was achieved.
