Abstract: A light emitting diode device is described which includes at least one planar non-periodic high-index-contrast grating. The light emitting diode device includes a cavity formed between a reflective optical element and a transmissive optical element. One or both of the optical elements can be a planar non-periodic high-index-contrast grating. The transmissive optical element can be a collimating lens used to collimate incident beams of light while the reflective optical element can be a parabolic reflector used to reflect incident beams of light along a direction opposite to an incidence direction. A light emitter can be disposed within the cavity and can emit beams of light.
