Abstract :
A classical model of spontaneous emission in resonant cavity light emitting diodes is developed. The model is based on a plane wave expansion of a randomly distributed ensemble of noninteracting optical dipole emitter pairs placed within a planar microcavity. The model accounts for losses due to leaky guided modes and intracavity absorption. Given an arbitrary device structure, the model predicts the total power emitted, the radiation pattern, and the relative magnitude of photocurrent generated in an intra or extracavity photodetector. Selected modeling results for an example device emitting at 650 nm are included
