Abstract

The spontaneous emission decay rate of light sources is determined both by intrinsic properties of the emitter, and by the Local Density of Optical States (LDOS). Spontaneous emission control is relevant for light-matter interaction studies, vacuum field engineering, in the areas of telecommunication and quantum computing. Control over the spontaneous emission decay rate can be used to make efficient light sources, solar cells, and low-threshold lasers. Photonic crystals can control emission over large volumes, as apposed to cavities.
