The id 200 photon-counting module, which works at telecom wavelengths, has been introduced by id Quantique SA. The device counts single photons between 1100 and 1600 nm. It works in gated mode and achieves a quantum detection efficiency higher than 10% at 1550 nm. The module offers subnanosecond jitter and a dark count probability smaller than 5e-5 per nanosecond. A stand-alone unit, the id 200 has a counter, display and an internal clock with synchronization output. Applications include quantum optics, fiber optic characterization, spectroscopy and eye-safe lidar.
