Abstract:
1. A method comprising forming a photonic crystal within a semiconductor structure, the semiconductor structure comprising a light emitting region configured to emit light of wavelength λ when forward biased, the light emitting region being disposed between an n-type region and a p-type region, wherein forming the photonic crystal comprises: forming a plurality of regions of semiconductor material having a first refractive index; and forming a plurality of regions of a material having a second refractive index, wherein the second refractive index is different from the first refractive index; wherein the regions of material having a second refractive index are disposed between the regions of semiconductor material in an array, and the material having a first refractive index is grown around the material having a second refractive index, and each region of material having a second refractive index is located less than 5λ from a nearest neighbor region of material having a second refractive index; and wherein the light emitting region is substantially planar and the regions of material having a second refractive index are confined to a region above or below the light emitting region.
