Princeton Lightwave’s 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
“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 mm. The SPAD
described in this datasheet is a back-illuminated device
provided in a pigtailed 14-pin butterfly package with a
single stage thermoelectric cooler.
