Abstract

Recent increasing interest in strain balanced Type-II superlattices material causing close attention from industry. Tremendous investment was drawn toward establishing strain balanced superlattice (SLS) as new alternative for infrared photodetectors across the broad range of infrared spectrum. In recent years, SLS material system has shown capability in particular specifications to compete with mature and standard mercury cadmium telluride for mid-wavelength and long-wavelength infrared detection. It has been great interest in SLS material system for applications aligned with the standard of third generation of infrared detectors. In that level, photodetectors with multi-color detection capabilities based on SLS material system are highly desired. In this presentation, some recent progress in three color infrared photodetectors based on SLS material system will be presented.
