ID Qube NIR Gated

ID Qube NIR Free-Running

ID230 Infrared Single-Photon Detector
The ID Qube NIR Gated is a fast-gated single photon detector optimized for telecom wavelengths.

The ID Qube delivers precise and reliable single-photon detection, with high quantum efficiency, low timing jitter and low detector noise. It provides a cost-effective solution for applications in which synchronous photon detection is essential, such as quantum communication and Quantum Key Distribution. It is also well suited to applications such as LiDAR where compactness is a key requirement.

The detector offers a gate input designed to avoid saturation or undesired detections and can also be operated in free-running mode.
The cooled InGaAs/InP avalanche photodiode and associated electronics have been designed to achieve especially low dark count and afterpulsing rates, even up to 100 MHz gated operations.

The ID Qube NIR Gated is available in free space or fibre-coupled (MMF 62.5 ?m FC/PC) versions.

  • Compact, cost-effective and dependable performance
  • Fast gated (up to 100 MHz) and free-running
  • Ultra-low noise (<800 cps at 10%)
  • Low jitter (<200 ps, typically <150 ps)
  • Free space or Fibre-coupled (MMF 62.5 ?m FC/PC) optical input
  • Broadband detection (900—1700 nm)
 The ID Qube NIR Free-Running brings a major breakthrough for single-photon detection in free-running operation at telecom wavelengths.It provides a cost-effective solution for applications in which asynchronous photon detection is essential, such as photon correlation or time of flight measurements. Moreover, it is especially suited for applications such as LiDAR, where compactness is a key requirement.

 This unique single photon detector based on InGaAs/InP avalanche photodiode working in Geiger mode provides fast avalanche quenching. That limits afterpulsing and allows you to run operations at reasonably short deadtimes which can be set between 2 us and 100 us. In addition, a new cooling system that can go down to – 90 °C gives the infrared single photon detector ID230 the lowest dark count rate available at the market. The ID230 single photon detector works thanks to an increased Stirling cooler with a very low afterpulsing probability and a timing resolution lower than 100 ps.

Low afterpulsing and dark count rate are combined with the best timing jitter and the highest quantum efficiency. The photon counting module can operate at detection probability levels of up to 25%.

  • Adjustable detection probability  from 0 to 25%
  • Adjustable deadtime from 2 us to 100 us
  • Adjustable temperature from -50 °C to -90 °C
  • TTL Output (100 ns, SMA connector)
  • Remote control via USB
