Abstract
Optical enhancement of light emitting devices. In accordance with an embodiment of the present invention, an apparatus includes an optical enhancement layer comprising nanoparticles. Each of the nanoparticles includes an electrically conductive core surrounded by an electrically insulating shell. The optical enhancement layer is disposed on a top semiconductor layer in a preferred path of optical emission of a light emitting device. The nanoparticles may enhance the light emission of the light emitting device due to emitter-surface plasmon coupling.
