Princeton Lightwave Introduces Single Photon Counting Avalanche Photodiodes With Fully Integrated Three-Stage Cooler

Cranbury, NJ -- Princeton Lightwave (PLI), the leader in single photon counting InGaAs/InP APDs, has introduced a line of single photon counting avalanche photodiodes with fully integrated thermoelectric coolers. The three-stage cooler, housed inside a hermetically sealed TO-8 package, is capable of achieving temperatures below -50°C without additional active cooling. These components utilize PLI's industry-leading InGaAs/InP avalanche photodetectors designed specifically for single photon counting applications. These devices are intended for use at bias voltages above the breakdown voltage (in the so-called "Geiger mode") so that a single photon incident on the detector will give rise to a readily detectable macroscopic current pulse. Combined with appropriate pulse detection circuitry, this device allows for the detection of single photons in the wavelength range from 0.9 to 1.6 µm.

The PGA-200 has a sapphire window with broadband anti-reflective coating and the PGA-308 has a standard single mode fiber with FC/UPC connector.
