Abstract :
We report continuous-wave room temperature operation of a GaAsSb-GaAs quantum-well vertical-cavity surface-emitting laser near 1.3 μm. The device is pumped with 674 nm light and provides 1-QmW total optical output at 1280 nm with 40% differential quantum efficiency. We describe the spatial, angular and spectral properties of the laser. This device sets a record for long wavelength with high output power in the GaAsSb-GaAs system.
