Status of quantum well infrared photodetector technology at QmagiQ today

The current state of focal plane arrays (FPAs) made from quantum well infrared photodetectors (QWIPs) is presented. In the last decade, QWIP technology has successfully transitioned at several companies from research and development to manufacturing and, today, represents a commercial success in cooled high-performance longwave infrared imaging. Technical performance metrics such as quantum efficiency, temporal and spatial noise, maximum frame rate and operating temperature, array uniformity and pixel operability, and manufacturing reproducibility are presented.
