Abstract
Microcavities are now being explored for their potential in controlling the radiative output from a variety of optical devices.1 The spectral and spatial distribution of the emission as well as the spontaneous emission rate may all be controlled by the structure and size of the microcavity. An important issue in microcavity design is the strength of coupling to the different decay channels available to the emitters. In particular, competition between radiative and nonradiative decay channels23 governs the efficiency of light emission in devices such as light-emitting diodes (LEDs) and lasers as well as the quantum yield of photovoltaic cells. The reported work addresses this issue by investigating emission from metal-clad microcavities.
