Abstract:
1. A light emitting device, comprising: an active region comprising semiconductor material; a first contact metal on the active region, the first contact metal having a first face adjacent the active region and a second face remote from the active region, and being sufficiently thin such that photons emitted by the active region pass through the first contact metal from the first face to the second face; a photon absorbing wire bond pad on the second face of the first contact metal, the wire bond pad having an area less than the area of the first contact metal; a reflective structure disposed entirely between the second face of the first contact metal and the wire bond pad and extending on the second face of the first contact metal to be substantially congruent with the wire bond pad; and a second contact metal opposite the active region from the first contact metal, wherein the reflective structure comprises a layer of silver or aluminum directly on the second face of the first contact metal.
