ABSTRACT: There has been significant progress in the development of infrared detectors and arrays (3-25mm) in the past decade. Infrared imaging has been an important technological tool for the past sixty years since the first report of infrared detectors in 1950s. New materials like InAsSb, InAs/GaSb superlattices and InAs/InAsSb superlattices have demonstrated very good performance. One of the unique aspects of the 6.1A family of semiconductors (InAs, GaSb and AlSb) is the ability to engineer the bandstructure to obtain designer band-offsets. Our group (http://www.krishnairlab.com) has been involved with the vision of the 4th generation of infrared detectors and is one of two university laboratories in the country that can undertake “Design to Camera” research and realize focal plane arrays.
