Abstract:
1. A light emitting device structure, comprising: a III-nitride based light emitting diode (LED) structure grown on an n-type Gallium Nitride (GaN) substrate, wherein: the LED structure comprises a III-nitride active layer positioned between at least a III-nitride p-type layer and at least a III-nitride n-type layer, a p-type electrode is deposited on or above the III-nitride p-type layer, the p-type electrode is transparent to the light emitted by the III-nitride LED structure, a submount, transparent to the light emitted by the LED structure, is attached to the p-type electrode, the GaN substrate is shaped to increase extraction of a first portion of light, emitted by the LED structure, from the GaN substrate and a first side of the light emitting device structure, a second portion of the light, emitted by the LED structure, is emitted from a second side of the light emitting device structure, and the GaN substrate is between the first side and the LED structure and the LED structure is between the second side and the GaN substrate.
