Continuous-wave operation of a 1.3microns GaAsSb/GaAs Quantum-Well Vertical-Cavity Surface-Emitting Laser at Room Temperature
01 September 2001
We report continuous-wave, room temperature operation of a GaAsSb/GaAs quantum-well vertical-cavity surface-emitting laser near 1.3microns. The device is pumped with 674 nm light and provides 1 mW total optical output at 1280 nm with 40% differential quantum efficiency. We describe the spatial, angular and spectral properties of the laser. This device features the record of long wavelength with high output power in the GaAsSb/GaAs system.
