Abstract

The authors calculate the current response of a superconductor-insulator-superconductor (SIS) to second order in photon operators and shows that, under certain conditions, an ideal SIS junction can be operated as a photon detector. The theory presented is a quantum generalization of the semiclassical diode theory developed by Werthamer (1966) and Tucker (1979). The dependence of the DC tunneling current on the number of photons present on the transmission line is shown. It is found that one electron tunnels for each photon absorbed by the junction.<>
