Light emitting device having a layer of photonic crystals and a region of diffusing material and method for fabricating the device

摘要

A light emitting device and method for fabricating the device utilizes a layer of photonic crystals and a region of diffusing material to enhance the light output of the device. The layer of photonic crystals is positioned over a light source, such as a light emitting diode die, and the region of diffusing material is positioned over the layer of photonic layer.
