Abstract

The molecular beam epitaxy growth conditions of a GaInAsSb/AlGaAsSb multi‐quantum wells stack have been successfully optimised. This included minimising the full‐width at half‐maximum of the high resolution X‐ray diffraction satellites and maximising the photoluminescence peak intensity collected at room temperature. Then, the optimised gain structures were successfully inserted in a) a microcavity and b) an external‐cavity Vertical Cavity Surface Emitting Laser. In both cases, room temperature laser operation near 2.3 µm in the continuous wave regime, with a circular single transverse mode output beam, was demonstrated. An output power larger than 1 mW at room temperature was measured. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
