Abstract: Comparative analysis for different topologies of superconducting single-photon detectors with ability to resolve up to 4 photons in a short pulse of IR radiation has been carry out. It was developed the detector with a system detection efficiency of ~ 85 % at λ = 1550 nm. The possibility of using such detector to restore photon statistics of a pulsed radiation source was demonstrated.

Abstract: Рассмотрена возможность применения сверхпроводникового нанополоскового детектора, разрешающего число фотонов (Photon-Number Resolving Superconducting Nanowire Photon Detector, PNR-SNPD), в качестве датчика приёмных модулей телекоммуникационных линий. Оценена мощность оптического импульса, необходимая для достижения приемлемо низкой доли ошибочных битов.

Abstract: We present the result of the creation and investigation of the multi-element superconducting single photon detectors, which can recognize the number of photons (up to six) in a short pulse of the radiation at telecommunication wavelengths range. The best receivers coupled with single-mode fiber have the system quantum efficiency of ⁓85%. The receivers have a 100 ps time resolution and a few nanoseconds dead time that allows them to operate at megahertz counting rate. Implementation of the multi-element architecture for creation of the superconducting single photon detectors with increased sensitive area allows to create the high efficiency receivers coupled with multi-mode fibers and with preserving of the all advantages of superconducting photon counters.
