Paper Abstract

Superconducting nanowire single photon detectors have recently been demonstrated as viable candidates for photon-counting optical receivers operating at data rates in excess of 100 Mbit/s. In this paper, we discuss techniques for extending these data rates to rates > 1 Gbit/s. We report on a recent demonstration of a 2-element nanowire detector array operating at a source data rate of 1.25 Gbit/s. We also describe techniques for emulating larger arrays of detectors using a single detector. We use these techniques to demonstrate photon-counting receiver operation at data rates from 780-Mbit/s to 2.5 Gbit/s with sensitivities ranging from 1.1 to 7.1 incident photons per bit.
