Time gated Superconducting Nanowire Single Photon Detectors

Enhance your signal-to-noise ratio with high precision filtering

Fast detector switch

In applications where background noise reduction and temporal filtering are crucial, the ability to swiftly activate and deactivate photon detectors is often essential.

Additionally, in experiments involving resonant excitation and collection, gating can be transformative for filtering out undesired photons, eliminating the need for cross-polarization techniques and their associated losses. For example, this approach is particularly advantageous in applications such as fluorescence spectroscopy, single-photon LiDAR, quantum communication, telecommunications, and microscopy.

Fast-gating technology

At Single Quantum, we’ve developed fast-gated SNSPDs capable of restoring full detection efficiency within just 5–20 nanoseconds. Our detectors operate using an externally clocked gate signal, allowing precise control — you can open and close the detector exactly when needed. Due to the inductive properties of the SNSPD, turn-on is not instantaneous; the time to reach full efficiency defines the minimum recovery time for gated experiments.
