SPD_A_M2 Single Photon Counter
Feb 2011
Aurea Technology
BESANÇON, France, Feb. 8, 2011 — The SPD_A_M2 manufactured by Aurea Technology is a family of ultralow-noise, high-quantum-efficiency near-infrared (900 to 1700 nm) single photon detectors. 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 × 10-6 per nanosecond.

They exhibit good sensitivity in high-level detection, making them more effective than photomultipliers and micro channel plate photomultipliers, according to the company. Most photomultipliers deliver quantum efficiency of <1% in the near-infrared, while the SPD_A_M2’s is adjustable from 5% up to 25%.

The RoHS-compliant devices provide plug-and-play connection to PCs via a USB interface, allowing users to easily adjust detection efficiency and to tune gate width and delay. They are supplied with a graphical user interface, but end users can develop their own with LabView or C++.

Optical fiber is single- or multimode, cooling time is <1 min at 25 °C, and peak detection is from 1150 to 1600 nm.

Applications include single photon counting, time-correlated single photon counting, quantum cryptography, failure analysis of integrated circuits, fluorescence, spectroscopy, eye-safe laser-ranging lidar, optical time domain reflectometry and quantum key distribution.
