Paper Abstract

In the literature, theoretical studies have indicated the quantisation of optical modes by cavity confinement may lead to enhancement of spontaneous emission factor (beta) . Placement of a radiating system within a cavity with a dimension the order of one wavelength alters the number of allowed optical modes to which photons couple. However, this does not guarantee enhancement. A typical semiconductor laser will be required to operate over a temperature range of at least 80 degree(s)C. Here we model the confinement of a radiating source between two DBR mirrors forming a planar microcavity and consider (beta) as a function of temperature where we use a calculated temperature dependent emission line, which the authors believe to be the first investigation including cavity effects. The results show that at threshold (beta) has a broad maximum with increasing temperature.
