Scientific paper

In recent years, many research groups in the world have demonstrated large format quantum well IR photodetector (QWIP) focal pane arrays for various thermal imaging applications. QWIPs as opposed to conventional low bandgap IR detectors, are limited by thermionic dark current and not tunneling current down to 30K or less. As a result the performance of QWIPs can be substantially improved by cooling from 70K to 30K. Cooling does not induce any nonuniformity or 1/f noise in QWIP focal plane arrays. In this paper, we discuss the development of highly uniform long-wavelength QWIPs for astronomical applications.
