In this paper we report a systematic investigation of emission properties of microcavity
devices [resonant-cavity light-emitting diodes (RC LEDs) and vertical-cavity surface-emitting
lasers (VCSELs)] fabricated from molecular beam epitaxy (MBE)-grown heterostructures.
The optimization of such structures requires proper tuning of the wavelength of radiation
emitted from the quantum-well active region, the peak reflectivity of Drs and the cavity
resonance. We demonstrate results of two techniques used to study InGaAs/GaAs RC LED …
