The Princeton Lightwave SPAD is an
InGaAsP/InP avalanche photo detector
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 1.1 um. The PLI SPAD described in this datasheet
is a back-illuminated device provided
in a standard three stage cooled
TO-8 can with a window cap.
