Visible Light Photon Counter

Source: Wikipedia, the free encyclopedia.

A Visible Light Photon Counter (VLPC) is a photon counting photodetector based on impurity-band conduction in arsenic-doped silicon. They have high quantum efficiency and are able to detect single photons in the visible range of the electromagnetic spectrum. The ability to count the exact number of photons detected is extremely important for quantum key distribution.

Rockwell International's Science Center had previously announced the "Solid-State Photomultiplier" (SSPM), a wide-band (0.4–28 µm) detector.[1] In the late 1980s a collaboration – initially consisting of Rockwell and UCLA – began developing scintillating-fiber particle trackers for use at the Superconducting Super Collider,[2][3] based on a dedicated variant of the SSPM that came to be known as the Visible Light Photon Counter.[4]

The operating principles are similar to

nanoseconds.[5]

VLPCs have been used extensively in the central tracking detector of the

D0 experiment,[8][9] and for muon beam-cooling studies for a muon collider (MICE).[7] They have also been evaluated for quantum information science.[6]
