The Princeton Lightwave Single Photon APD ( SPAD ) is an InGaAs/InP avalanche photodetector designed specifically for single photon counting applications. The device is intended for use at voltage biases above the breakdown voltage (in the so-called “Geiger mode”) so that a single photon incident on the detector will give rise to a
macroscopic current pulse. Combined with appropriate pulse detection circuitry, this device allows for the detection of single photons in the wavelength range from 0.95 to 1.65 um.
The PLI SPAD described is available in a pigtailed butterfly package with a one stage cooler.
