- Superconducting nanowire single-photon detector - Wikipedia
The SNSPD consists of a thin (≈ 5 nm) and narrow (≈ 100 nm) superconducting nanowire The length is typically hundreds of micrometers, and the nanowire is patterned in a compact meander geometry to create a square or circular pixel with high detection efficiency
- Single Quantum - Excellence in photon detection
Single Quantum multi-channel SNSPD system can detect single photons with over 90% efficiency and ultra-high timing resolution of less than 15 ps
- Single-Photon Detectors | NIST
The superconducting nanowire single-photon detector (SNSPD) is made of a thin film of superconducting material that covers an active detection area as a meandering nanowire
