Room-temperature continuous and pulsed lasing of vertical-cavity, single-quantum-well, surface-emitting microlasers is achieved at approximately 983 nm. The active Ga/sub 0.8/In/sub 0.2/As single quantum well is 100 AA thick. These microlasers have the smallest gain medium volumes among lasers ever built. The entire laser structure is grown by molecular beam epitaxy and the microlasers are formed...
