Abstract
Cascaded InAs/GaSb superlattice light emitting diodes are being developed for broadband, high radiance light sources for spectroscopy, and advanced technologies using large format arrays. Cascading is shown to allow broadening of the SLED spectral output, tuning of the electrical characteristics, and boosting of the maximum output power and efficiency. Wallplug efficiencies are found to be low, but internal quantum efficiency very high. It is anticipated that external quantum efficiency can be significantly increased by using strategies to help extract the light from these high index materials.
