Abstract
A high efficiency Group III nitride light emitting diode is disclosed. The diode includes a Group III nitride-based light emitting region including a plurality of Group III nitride-based layers. A lenticular surface directly contacts one of the Group III nitride-based layers of the light emitting region. The lenticular surface includes a transparent material that is different from the Group III nitride-based layer of the light emitting region that the lenticular surface directly contacts.
