We developed superconducting nanowire single-photon detectors (SNSPDs) based on tungsten silicide (WSi) that show saturated internal detection efficiency up to a wavelength of 10 um. These detectors are promising for applications in the mid-infrared requiring ultra-high gain stability, low dark counts, and high efficiency such as chemical sensing, LIDAR, dark matter searches and exoplanet spectroscopy.

  1. Gravitational Photon Polarization Twist to Probe the Early Universe and the Galactic Center

    hep-ph 2025-07 conditional novelty 6.0 of 10

    A long-baseline laser pulse whose polarization is twisted by gravitational waves could detect galactic-center pulsar and early-universe gravitational wave backgrounds.

  2. High-Frequency Gravitational Waves on BREAD

    hep-ph 2025-05 conditional novelty 6.0 of 10

    BREAD with single photon detectors could detect high-frequency gravitational waves at 0.05 to 200 THz, with projected strains as low as 1e-25 at 200 THz.
