Photon absorption in a superconducting strip with a thickness of only a few nanometers produces excited quasiparticles eventually produce a localized resistive region. A Superconducting Strip Photon Detector （SSPD） based on this phenomenon was proposed in 2001, and today, the detection efficiency is approaching 100 %, the dark count rate and timing jitter is overwhelmingly low as compared to other single photon detectors. SSPD has already positioned as an indispensable technology in various advanced technological fields such as quantum technology, live cell observation, LIDAR, and deep space optical communication technology. Recently, there have been several reports that break down stereotypes about what an SSPD should be. In this article, I focus on intriguing topics concerning the latest research and development trends in SSPD.

Superconducting nanowire single-photon detectors (SNSPDs) are the leading technology for photon counting at near-infrared wavelengths, offering unparalleled performance across multiple metrics and enabling diverse applications. Two decades after their introduction, SNSPDs have made significant progress and reached a mature stage of development. However, the requirements of new, demanding applications and the push to democratize this technology open up new opportunities for further advancements. In this perspective, we provide an introduction to SNSPD technology, an overview of current research trends, and insights into future directions in this field.
