Single Photon Benchtop Receiver PGA-600
The Princeton Lightwave Photon Counting Benchtop Receiver is a complete solution for single photon counting applications such as quantum optics. The receiver integrates an InGaAs Single Photon Avalanche Photodiode (SPAD) with all the necessary bias and control electronics. The InGaAs SPAD has been specially designed for single photon counting to provide high detection efficiency and low dark count rate. The unit’s electronics utilize a patented technique to improve system performance. The front panel of the unit displays the number of photons detected in a selected interval as well as diagnostic information. All operating parameters and values can also be accessed through the RS-232 interface. The receiver is packaged in a 3U 19” rack mount chassis.
Pigtailed Cooled Single Photon Counting Avalanche Diode (SPAD)
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 um. 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.
Pigtailed Coaxial Single Photon Counting Avalanche Photodiode The Princeton Lightwave 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. |
