Patent ID: 8643036

Claim:
A method of fabricating a semiconductor light emitting device, comprising: selectively texturing a surface of a layer in order to produce light emissions at two or more peak wavelengths from different locations on the selectively textured surface; and incorporating varying fractions of indium at the different locations on the selectively textured surface by depositing one or more indium-containing light-emitting Group-III nitride layers on or above the selectively textured surface, wherein the one or more indium-containing light-emitting Group-III nitride layers incorporate the varying fractions of indium depending on a position on the selectively textured surface, with a higher incorporation of indium at a top of a pillar on the surface, as compared to a lower incorporation of indium in a valley between pillars on the surface, and an intermediate incorporation of indium on side-walls of the pillars.
