Abstract
The room temperature operation of visible vertical cavity surface emit ting lasers at 642 nm is reported. A pulsed threshold current of 45 mA for a 26 mu m diameter mesa device (corresponding to 8.5 kA cm(-2)) w as achieved at an operating voltage of 3.5 V. Photoluminescence at 10 K showed that an In0.48Al0.3Ga0.22P direct barrier provides better ele ctron confinement than an In0.48Al0.52P indirect barrier with unstrain ed In0.48Ga0.52P quantum wells.
