Patent Images
1. A light emitting device comprising:
- a multi-layer stack of material including an n-doped region, a p-doped region and a light generating region disposed between the n-doped and p-doped regions, wherein at least a portion of the light generated from the light generating region emerges from the light emitting device via a top emission surface of the multi-layer stack of materials; and
a wavelength converting material layer disposed according to a pattern on the top emission surface of the multi-layer stack of material, wherein sidewalls of the multi-layer stack of material are substantially devoid of the wavelength converting material.
