20100303414CHIP-BASED SLOT WAVEGUIDE SPONTANEOUS EMISSION LIGHT SOURCES - An optical device includes an optically emitting material producing spontaneous emission and an optical waveguide coupled to the optically emitting material. The spontaneous emission from the optically emitting material is emitted into at least one optical mode of the optical waveguide. The optical waveguide coupled to the optically emitting material does not provide optical gain, and the presence of the optical waveguide causes the spontaneous emission rate to be substantially more rapid than in the absence of the optical waveguide. The optical waveguide causes the more rapid spontaneous emission rate over a broad range of frequencies.12-02-2010
