In this webinar hosted by the OSA Laser Systems Technical Group, Dr. John Prineas from the University of Iowa will present an overview of his research on InAs/GaSb mid-wave, cascaded superlattice light emitting diodes.
InAs/GaSb mid-wave, cascaded superlattice light emitting diodes (SLEDs) have been heavily developed for high power infrared emitter arrays such technologies as thermal scene generation. They started life as a promising material for infrared focal plane arrays for thermal imaging due to the possibility of Auger suppression, which limits narrow gap semiconductor performance, through bandstructure engineering. SLEDs have been demonstrated with cascading, multi-spectral output, on foreign substrates with no degradation in output power, and in arrays of increasing dimensions. Arrays with apparent temperatures hotter than the surface of the sun are envisioned.
