Superconducting Nanowire Single Photon Detector Arrays for Time-Resolved Imaging and Infrared Detection

Superconducting Nanowire Single Photon Detectors (SNSPDs) are the most advanced detectors available for time-resolved single photon counting from the UV to the long-wavelength infrared. Recent advances in nanofabrication and multiplexing have enabled the ability to scale to large cameras of SNSPDs, to create fully digital event-driven single-photon cameras for time-resolved imaging. This enables transformative new capabilities in a wide range of scientific areas, including quantum computation, remote sensing, biomedical imaging, deep-space optical communication, and astronomy. In this talk, we will summarize recent progress toward megapixel-scale SNSPD cameras, and the path to scale these cameras up in the future. We will also discuss recent progress in extending the wavelength range of SNSPDs to far-infrared wavelengths, including time-resolved single-photon counting at wavelengths as long as 88 µm, and integration of devices with antennas at 25 µm.
