Deep-red continuous wave top-surface-emitting vertical-cavity AlGaAs superlattice lasers

Deep-red (770-nm) top-surface-emitting vertical-cavity AlGaAs lasers were fabricated and operated continuously at room temperature. An Al/sub 0.14/Ga/sub 0.86/As superlattice was used for an active-gain medium. Efficient current funneling was achieved by deep proton implantation. Continuous-wave (CW...
