Current status of quantum well focal plane arrays

William A Beck, Thomas S. Faska

Open publisher page 27 citations

Abstract

The state of the art in quantum well infrared photodetectors (QWIPs) is reviewed, with emphasis on the current status of QWIP focal plane arrays (FPAs). These FPAs are progressing rapidly in size from 256 by 256 to 640 by 480 pixels, and typically have temporal and spatial noise below 20 mK when operated up to 77 K in an f/1.7 camera system. Frames from videotapes recorded with recent FPAs are presented.
