Operation Principle

Based on a breakthrough techonology, superconducting nanowire single photon detector (SNSPD), Single Quantum develops the fastest and most sensitive light sensors on the market.

The high efficiency single photon detector chips incorporate thin films of superconducting material shaped into meandering nanowires. The nanoscale cross section gives our detectors extremely high sensitivity upon absorption of just a single photon. Robust and efficient fiber coupling guarantees the best performance at cryogenic temperatures.

With superior detection efficiency and high time resolution, Single Quantum’s SNSPDs outperforms avalanche photodiodes (APDs) in the near infrared and offer many more favorable features.
