Paper Abstract

Far infrared photoconductive detection is considered in the wavelength range 30 to 1000)π m. High sensitivity direct detection in a low photon flux background, as typically met in spaceborne astrophysics measurements, is emphasized. Recent advances in extrinsic germanium photoconductors, particularly stressed Ge:Ga are reported. Wideband photoconductive detection with Hgi-xCdxTe and narrow band magnetically tunable photodetection based on InSb and GaAs are reviewed. Prospects for new devices and supporting technologies are discussed.
