Light emitting diodes (LEDs) incorporating InAs-GaSb superlattices (SLs) and multiple SL regions coupled with tunnel junctions are described. The studies have shown that saturation of optical output is because of both carrier leakage and Joule heating, with the latter being responsible for output limitations and device failure in large mesas.
