Paper Abstract

Many of the recent advances in infrared astronomy in the 1 - 5 μm region have been the result of efforts to utilize and optimize indium antimonide (InSb) detectors for this application. This paper will briefly review the progress which has been made in obtaining 2 μm NEP values as low as 10-16w-Hz-1/2 with photovoltaic InSb. More recent efforts have concentrated on other types of InSb operation, such as CID's and CCD's, which are more suited to array formats for spectroscopic and imaging applications. Advances in the fabrication of InSb photodiodes makes possible the integration of photocurrent on the detector capacitance, with the potential of measuring infrared fluxes of a few photon/s during integration times > 1000 s.
