ID281 Superconducting Nanowire

The very best in single-photon detection, with ultra-stable performance

  • Near-ideal detection efficiency: can exceed 95%
  • Highly precise timing and low noise, true latch-free operation
  • Ultrafast and photon-number resolving detection
  • Mix and match up to 16 detectors, with options for rack-mounted systems

Push the limits of your photonic experiments and applications to new heights with our Swiss-made superconducting nanowire single-photon detectors (SNSPDs), combining incredibly high detection efficiency, timing precision, low noise and fast recovery time.

In a single ID281 system, mix and match up to 16 detectors, available in a range of specifications customizable to each user, including our Standard (single-pixel), Ultrafast (parallel-pixel) and Photon-Number-Resolving/PNR (parallel-pixel) options.

For added convenience and mobility, the full ID281 system is also available in a range of self-contained rack-mounted solutions.


Near-ideal detection efficiency

Every ID281 SNSPD has a high system detection efficiency (SDE) across hundreds of nanometres, centred on a user-selected wavelength from <635 nm to >2000 nm.

  • Every Standard SNSPD: > 80% SDE
  • High-spec Standard SNSPDs: > 90% SDE (and can exceed 95%)
  • Photon-number-resolving SNSPDs: > 70% SDE (typically >80%)
  • Ultrafast SNSPDs: > 70% SDE (typically >80%)

For even broader wavelength ranges, custom optical cavities can be designed and detectors can be coupled to multimode fibre on request.

High precision

With built-in cryogenic amplifiers, the detector timing jitter is < 50 ps FWHM for all Standard SNSPDs, and can reach as low as < 30 ps.

Fast recovery

All single-photon detectors have a finite time in which they need to “reset” after a detection event.

  • Standard ID281 SNSPDs recover to 50% of the peak SDE within 80 ns (typically < 60 ns)
  • Ultrafast ID281 SNSPDs recover to 50% of the peak SDE within 20 ns (typically < 10 ns)

Ultra-low noise

Detector dark counts are always low, decrease at shorter wavelengths, dominated by black-body radiation.

  • < 100 Hz at 1310—1550 nm
  • < 20 Hz at 950—1064 nm
  • < 5 Hz at 635—950 nm
