In the work, Chandra Mouli Natarajan, Mike Tanner and Robert Hadfield from Heriot-Watt University, UK, survey advances made by research groups around the world in this technology. The first part of the review concerns the basic SNSPD operating principle, the evolution of device design and origins of noise mechanisms. Next, practical refrigeration technologies and optical coupling schemes for SNSPDs are discussed. The article concludes with a comprehensive survey of promising application areas.
