  • Photon detector and process for detecting a single photon
    Patent number: 9401448
    Abstract: A photon detector article includes a photon detector configured to receive a primary waveform, the photon detector includes a multiplication region; a photon absorption region; a punch through voltage range; and a breakdown voltage; a source in electrical communication with the photon detector and configured to provide the primary waveform that includes a first voltage that is: less than a maximum value of the punch through voltage range, or effective to maintain a charge carrier in the absorption region; and a second voltage that is greater than the breakdown voltage; and a reference member in electrical communication with the source and configured to provide a reference waveform in response to receiving the primary waveform.
    Type: Grant
