Discrete Single Photon Avalanche Diodes |
|
Princeton Lightwave designs and manufactures the
highest performance Single Photon Avalanche Diodes (SPADs)
available for single photon detection in the
short-wave infrared (SWIR) wavelength range from 0.9
to 1.6 µm. PLI’s SPADs have been optimized for
Geiger-mode operation, which provides a macroscopic
avalanche current pulse in response to just a single
photon. When combined with appropriate bias and
pulse discrimination circuitry, the SPADs provide
high photon detection efficiency, very low dark
count rates, and high photon counting repetition
rates. These detectors are available in a variety
of product formats, including modules providing
free-space coupling, fiber-coupling, integrated
thermoelectric cooling (TEC), and turnkey receiver
instruments. |

| Self-Quenching Negative Feedback Avalanche Diodes |
Princeton Lightwave’s PNA-20X series NFAD is a new breed of photon-counting device consisting of InGaAs/InP avalanche diodes with monolithically integrated negative feedback to provide stable high-performance single photon response in Geiger mode operation. PLI’s NFAD has excellent photon-counting capability in the shortwave infrared (SWIR) band, with high internal gain (10^5 to 10^6), very consistent pulse response distributions, and fast response coupled with excellent timing resolution.
The NFAD operates with just a simple DC bias voltage and does not require any gating or quenching circuitry.
