Abstract

Liquid-nitrogen cooled quantum-well infrared photodetectors (QWIP) provide high response and high-speed detection of 10-micron radiation. When processed with high doping, QWIP's have been found to provide sensitive detection for long-wavelength infrared radiation at elevated temperatures. Experimental measurements using both direct and heterodyne detection show excellent performance at 10 microns and at temperatures up to 300 degrees-Kelvin. This high temperature operation allows applications in small or power limited platforms and significantly reduces the cost of the infrared detection system. Although only single element detectors have been evaluated, linear and 2-D arrays are expected to have similar performance characteristics. Experimental results for both video and heterodyne detection will be presented.
