Abstract
The first electrically injected visible InAlGaP/AlGaAs vertical cavity surface emitting lasers are reported. The devices consist of an InAlGaP optical cavity active region surrounded by AlAs/AlGaAs distributed Bragg reflectors. Pulsed room temperature lasing has been observed at wavelengths from 639 to 661 nm. At 650 nm, thresholds of 30 mA at 2.7 V were measured on test devices with a 20 mu m emission diameter. Peak output power exceeds 3.3 mW.
