Advances in superconducting nanowire devices for UV to mid-infrared single-photon detection

In recent years, superconducting nanowire single-photon detectors (SNSPDs) have emerged as the state-of-the-art for photodetection in infrared regime. However, there are technical challenges still need addressing, such as high non-uniformity in SNSPD arrays, high polarization sensitivity, lack of cryogenic ROIC, and lack of high-performance devices in the mid-IR regime. During this talk, I will discuss our current work on overcoming some of these challenges.
