Laser Focus World Webcast 'Infrared superconducting single photon detectors'
I will be giving a webcast entitled 'Infrared superconducting single photon detectors' on monday 27th February 2012 at 4pm GMT.
Abstract:
Infrared photon counting detectors are a key enabling technology for a host of applications at the frontiers of science. In the past decade, single photon detectors based on superconducting nanowires have emerged as an alternative to established photon-counting technologies such as photomultipliers and avalanche photodiodes. These new devices offer infrared single photon sensitivity with low dark counts, free running operation and excellent timing resolution. I will discuss the evolution of superconducting single-photon detector technology, practical implementations and future avenues for development. I will then highlight several promising application areas for these detectors: characterization of quantum emitters, time-of-flight ranging, fiber Raman temperature sensing and quantum key distribution.
Register via the Laser Focus World Website to follow the talk online and participate in the Q & A.
