| Cranbury, N.J., January 15, 2007 Princeton Lightwave (PLI) the leader in InGaAs APDs introduces the next
generation Single Photon Counting Bench-top Receiver for wavelengths from 1 to 1.5 µm.
The receiver offers the lowest dark count rate in the industry with highest detection efficiency.
The low dark count rate is obtained by using PLI’s custom InGaAs Single Photon Counting Avalanche Photodiode (SPAD).
In addition, the receiver offers an easy to use interface and remote operation.
The Single Photon Counting Bench-top Receiver has a comprehensive measurement in the range from 1 to 1.5 µm.
The unit can operate from either the internal frequency generator or an external trigger at rates up to 20 MHz.
An output from the internal frequency generator can be used to synchronize other equipment such as a laser source.
All operating parameters such as bias voltage, SPAD temperature, trigger delay, and measurement interval are controlled from the
front panel or through the RS-232 interface.
The unit displays the number of photons detected as well as the number of trigger pulses in a user defined interval.
The Single Photon Counting Bench-top Receiver provides the best optical performance on the market.
The minimum detection efficiency of every unit is at least 25%.
The typical dark count rate is 2 x 10-5 per trigger when operated with a 1 ns gate and 20% detection efficiency.
The receiver comes with several upgradeable options such as multi mode fiber interface,
optimized SPAD performance for a particular wavelength,
and a short pulse Fabry-Perot laser source that generates sub-500 ps pulses.
Adding an optical attenuator creates a single photon source.
Applications for the Bench-top Receiver include quantum key distribution, quantum computing and other quantum optics experiments.
For measurements of coincidence the unit can accoµmodate two receivers.
Each receiver unit has its own interface but both units can be driven from one internal frequency generator.
Princeton Lightwave will exhibit the receiver at booth 6114 at Photonics West, San Jose, California January 23rd to 25th.
