Abstract

Wave-guiding mechanisms in large area verticalcavity surface-emitting lasers (VCSEL's) 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.
