Abstract

We demonstrate a novel epitaxial process for the growth of low-dislocation density GaSb on GaAs. The growth mode involves the formation of large arrays of periodic 90° misfit dislocations at the interface between the two binary alloys which results in a completely strain relieved III-Sb epi-layer without the need for thick buffer layers. This epitaxial process is used for the growth of antimonide active regions directly on GaAs/AlGaAs distributed Bragg Reflectors (DBRs) resulting in 2 μm VECSELs on GaAs substrates.
