Abstract:
1. A microcavity light emitting diode, comprising: a semiconductor active layer comprising Al at least one semiconductor n-type layer comprising Al at least one semiconductor p-type layer comprising Al an electrical contact coupled to the at least one semiconductor n-type layer; a reflective electrical contact coupled to the at least one semiconductor p-type layer and the at least one semiconductor n-type layer, the reflective electrical contact having a reflectivity greater than about 70% at the peak emission wavelength; a total thickness characterizing the semiconductor active layer, the at least one semiconductor n-type layer, and the at least one semiconductor p-type layer of less than 6λ/n; and a uniformity to within approximately ±λ/(4n) wherein n is a thickness averaged index of refraction at the peak emission wavelength characterizing the total thickness of the semiconductor active layer, the at least one semiconductor n-type layer, and the at least one semiconductor p-type layer.
