The Princeton Lightwave Single Photon APD ( SPAD ) is an InGaAs/InP avalanche photo-detector designed specifically for single photon counting applications. The device is intended for use at voltage biases above the break-down voltage (in the so-called “Gei-ger mode”) so that a single photon detector will give rise to a macro-scopic 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 is a back-illuminated de-vice provided either in a standard uncooled TO-46 can or in a three stage cooled standard TO-8 can.
