Superconducting nanowire single photon detectors (SNSPDs) are the most advanced sensors available for time-resolved single photon counting from the ultraviolet to the infrared. We will discuss recent advances in SNSPD technology in the US, including scaling to large-format arrays (up to 400 kpix), single-photon sensitivity at wavelengths as long as 29 µm, ultra-high time resolution (as short as 3ps FWHM at visible wavelengths), and ultra-high count rates (1.5 Gcps). We will discuss recent applications of SNSPD technology in deep-space optical communication projects such as DSOC and Optical-to-Orion (O2O), as well as potential future applications of the technology in astronomy, quantum communication, dark matter detection, and biomedical imaging.
