Linear Avalanche Photodiodes Enable Single Photon Sensors   April 1, 2008
By: Ayub Fathimulla,Harry Hier,Jim Foshee,Leye Aina,Sachi Babu,Sensor Directorate (AFRL/RYTD)

Single photons are elementary particles that are arguably the most tangible, yet some of the most difficult to detect and characterize as single entities. Techniques to count single photons require optical detectors with linear operation, high gain, wide bandwidth and low noise. This article will...more >>
