Superconducting Hot Electron Mixers for Fiber Optics

Abstract

The main objective of this grant was research and development of superconducting NbN hot-electron photodevices for the optical-to-electrical signal conversion with a speed of 30 Gb/s. The program was realized as a direct collaboration between the Moscow State Pedagogical University (MSPU) and the University of Rochester (UR). As the demonstration project, we developed an integrated superconducting fiber-optic signal-processing unit, consisting a hot-electron NbN device and a broadband amplifying circuitry, operational at liquid helium temperatures. We measured the quantum photon yield of our devices, as well as their time-resolved, picosecond response. The MSPU-UR work coordination included a united research program for both groups, joint measurements in Moscow and Rochester, expeditious exchange of experimental samples and results, and electronic conferencing.
