Optical/UV single-photon imaging spectrometers using superconducting tunnel junctions

Abstract

We present preliminary test results of optical/UV single-photon imaging spectrometers using superconducting tunnel junctions. Our devices utilize a lateral trapping geometry. Photons are absorbed in a Ta thin "lm, creating excess quasiparticles. Quasiparticles di!use and are trapped by Al/AlO x /Al tunnel junctions located on the sides of the absorber. The… (More)
