PT Unknown AU Gershenzon, EM Gol'tsman, GN TI Hot-electron superconducting mixers SE Proc. SPIE PY 1993 BP 329 EP 330 VL 2104 DI 10.1117/12.2298564 AB The creation of low noise heterodyne receivers for frequencies above 1 THz is in the urgentneed for radio astronomy, laser spectroscopy, plasma diagnostic, etc. In this paper we discussthe nonlinear effect related to hot electrons in superconductors, and their potential use in lownoise submilimeter wave mixer. We also discuss results achieved so far as well as possible futuredevelopments. ER
