Single Photon Counting Modules for Quantum Cryptography Applications
Product Presentation at Photonics West: COUNT® NIR and COUNT® Q
(PresseBox) (Olching, )LASER COMPONENTS presents two new Single Photon Counting Modules at BiOS and Photonics West 2013: COUNT® NIR and COUNT® Q. Both are optimized for longer wavelengths.
COUNT® NIR. The COUNT® NIR features an APD with enhanced detection efficiency around 810 nm. This wavelength plays an important role in quantum cryptography applications. The outstanding performance of the various photon counting modules produced to date is based on a proprietary APD design that was developed by the LASER COMPONENTS Detector Group out of Arizona. This is what gives LASER COMPONENTS the opportunity to take the technology to where their customers need it to be.
COUNT® Q. An absolute highlight is the COUNT® Q. Many of the customers work at wavelengths that silicon does not cover any more. The COUNT® Q features an integrated InGaAs APD and covers the spectral range from 900 nm to 1600 nm. For best performance, the APD is thermoelectrically cooled. Just like the silicon APD-based COUNT® modules the focus during the development of the COUNT® Q has been on high detection efficiency and low dark current.
