Paper Abstract

One of the simplest device realizations of the classic particle-in-the-box problem of basic quantum mechanics is the quantum well IR photodetector (QWIP). In this paper we discuss the optimization of the detector design, material growth and processing that has culminated in realization of 15 micron cutoff 128 X 128 QWIP focal plane array camera, hand-held and palmsize 256 X 256 long wavelength QWIP cameras and 648 X 480 long-wavelength cameras, holding forth great promise for myriad applications in 6-25 micron wavelength range in science, medicine, defense and industry. In addition, we present the recent developments in broadband QWIPs and mid-wave long-wave dualband QWIPs at Jet Propulsion Lab for various NASA and DOD applications.
