Abstract

Wave-guiding mechanisms in large area InGaAs-GaAs MQW vertical-cavity surface-emitting lasers (VCSELs) have been investigated using novel spatially and spectrally resolved measurements of spontaneous and stimulated emission. Carrier induced anti-guiding is found to be important despite the presence of other guiding mechanisms.
