Thermally Coupled Imager for Performing Time and Position Sensitive Imaging of Single Photons
Published Patent Application Number: 17/512,279
Although, superconducting nanowire single photon detectors (SNSPD)s are the leading technology for single photon detection, featuring high count rates (>100 MHz), low timing jitter (<5 ps), and low dark counts(< 1 Hz), the efficient multiplexed readout of N pixels with many fewer than N wires remains an unsolved challenge.
Invention
A SNSPD imager which will be capable of reading out at least tens of thousands of detectors. This array, the SNSPD "thermally-coupled imager" (TCI) efficiently multiplexes SNSPDs on a single readout line and is capable of resolving both location and time-of-arrival of single photons over a large {> 1 mm) area.
Applications/Industries
SNSPD detector companies Quantum opus Space communications Photonic quantum computing companies using SNSPDs Astronomy.
Market
Broad range of applications, and capability of operating efficiently in a very broad range of wavelengths.
