Abstract
The disclosure describes various aspects of using optical elements monolithically integrated with light-emitting diode (LED) structures. In an aspect, a light emitting device includes a single LED structure having an active region and a single optical element disposed on the LED structure and configured to collimate and steer light emitted by the LED structure. One or more additional optical elements may also be disposed on the LED structure. In another aspect, a light emitting device may include multiple LED structures and a single optical element disposed on the multiple LED structures and configured to collimate and steer light emitted by the multiple LED structures. For each of these aspects, the LED structure(s) and the optical element(s) are made of a material that includes GaN, the LED structure(s) has a corresponding active region, and the LED structure(s) has a corresponding reflective contact disposed opposite to the optical element(s).
