Abstract:
1. At least one light emitting diode, comprising: a first doped semiconductor layer, wherein said first doped semiconductor layer has a first surface, a second surface opposite and substantially parallel to said first surface and an edge surface that connects said first surface and said second surface, wherein said first doped semiconductor layer is a current spreading layer; an active region underlying and in contact with said second surface of said first semiconductor doped layer, wherein said active region emits light; a second doped semiconductor layer underlying and in contact with said active region; a first electrode, wherein said first electrode is in contact with said edge surface of said first doped semiconductor layer; and a second electrode underlying and in contact with said second doped semiconductor layer, wherein said second electrode includes an optically transparent layer underlying and in contact with said second doped semiconductor layer and a reflective conductive metallic layer underlying and in contact with said optically transparent layer.
