Abstract
The use of superconductivity in IR focal plane arrays can offer many significant advantages over present semiconductor technology. This paper outlines a number of these advantages as well as tracing the evolutionary development of these radically new detector systems. Data on the first superconducting SQUID amplifiers for use with these systems is presented. Information on a new low-power dissipation superconducting transimpedance amplifier that can match the impedance between conventional semiconductor detectors and superconducting electronics is also presented. The concept of using extremely wide bandwidth optical antenna as opposed to direct photo-absorption in a superconducting detector element is discussed and the advantages of this approach outlined. A demonstration program with detectors having NEPs $OM 10-15 is described.
