Abstract: A photon detector system for detecting photons emitted from an optical fiber, the photon detector system comprising a receiving mechanism for receiving the optical fiber; a photon detector comprising a superconducting element and aligned with the receiving mechanism, the photon detector having an active area for detecting photons emitted from an end-face of the optical fiber received in the receiving mechanism and an urging mechanism for urging together the photon detector and the optical fiber.
