1. A device comprising:
- a III-nitride semiconductor structure including an active region disposed between a first n-type region and a p-type region;
a photonic crystal structure disposed in at least a portion of the first n-type region;
a second n-type region disposed between the photonic crystal structure and the active region; and
a reflector disposed on at least a portion of a surface of the p-type region opposite the active region;
wherein a top surface and a bottom surface of a structure comprising all semiconductor layers in the device are uninterrupted by the photonic crystal structure.

Abstract
A photonic crystal structure is formed in an n-type region of a III-nitride semiconductor structure including an active region sandwiched between an n-type region and a p-type region. A reflector is formed on a surface of the p-type region opposite the active region. In some embodiments, the growth substrate on which the n-type region, active region, and p-type region are grown is removed, in order to facilitate forming the photonic crystal in an n-type region of the device, and to facilitate forming the reflector on a surface of the p-type region underlying the photonic crystal. The photonic crystal and reflector form a resonant cavity, which may allow control of light emitted by the active region.
