Abstract

A light emitting diode is disclosed that includes an active structure, a first ohmic contact on the active structure, and a transparent conductive oxide layer on the active structure opposite the first ohmic contact. The transparent conductive oxide layer has a larger footprint than said active structure. A dielectric mirror is positioned on the transparent conductive oxide layer opposite said active structure and a second contact is positioned on the transparent conductive oxide layer opposite the dielectric mirror and separated from the active structure.
