Abstract

Continuous wave (CW) operation at room temperature of electrically pumped InGaAlAs/InP vertical-cavity surface-emitting lasers (VCSELs) at emission wavelengths as high as 2.3m is demonstrated for the first time. Devices with 15m active region diameter show a maximum output power of 0.75mW at 20°C and a maximum CW operating temperature of 45°C.
