Abstract :
The continuous-wave room-temperature operation of an electrically pumped 1.55 μm wavelength vertical-cavity surface-emitting laser (VCSEL) with up to 1.7 mW output power is reported. The laser comprises an optimised multi-quantum-well active region and an improved mirror design for reduced optical losses.
