The SPD_A_M2 ultralow-noise, high-quantum-efficiency near-infrared
(900 to 1700 nm) single-photon detectors are manufactured by Auréa Technology.
Their Geiger-mode InGaAs avalanche photodiode and thermoelectric cooler ensure high
detection efficiency, a low and stable dark count, high speed and low jitter, with
a performance superior to 5 x 10–6 per nanosecond. They exhibit good sensitivity
in high-level detection, making them more effective than photomultipliers and microchannel
plate photomultipliers, according to the company. Most photomultipliers deliver
quantum efficiency of <1% in the near-infrared, while that of the SPD_A_M2 is
adjustable from 5% up to 25%. The RoHS-compliant devices provide plug-and-play connection
to PCs via a USB interface. Applications include single-photon counting, time-correlated
single-photon counting, fluorescence and spectroscopy.
