Abstract:
A device emitting mid-infrared light that comprises a semiconductor substrate of GaSb or closely related material. The device can also comprise epitaxial heterostructures of InAs, GaAs, AlSb, and related alloys forming light emitting structures cascaded by tunnel junctions. Further, the device can comprise light emission from the front, epitaxial side of the substrate.

Claim (Index 20):
A light-emitting diode die emitting mid-infrared light, the light-emitting diode die comprising:\n a semiconductor substrate of GaSb; epitaxial heterostructures located on the semiconductor substrate and forming an epitaxial side of the substrate, wherein the epitaxial heterostructures form light emitting structures cascaded by tunnel junctions; wherein the epitaxial side of the substrate is configured to emit light formed by the epitaxial heterostructures; and\n a metal mesh structure in contact with an n-type InAs layer to form a low-resistance ohmic contact, the mesh structure comprising: a first portion comprising eight or more small metal mesh lines directly above and directly contacting the n-type InAs layer; \n a second portion comprising four thick metal mesh lines, wherein each one of the four thick metal mesh lines extends directly away from a common point, wherein the first portion is between the InAs layer and the second portion, wherein each of the eight or more small metal mesh lines have a smaller thickness than each of the four thick metal mesh lines, wherein the first portion comprises mesh openings in the metal mesh structure, the four or more thick metal mesh lines comprise a width of 20 \u03bcm, the eight or more small metal mesh lines comprise a width of 5 \u03bcm and a thickness of 1 \u03bcm, and the mesh openings comprise openings of 50 \u03bcm across, and \n wherein the metal mesh structure is configured to spread current evenly across the light-emitting diode die while allowing light extraction.
