	Moshkova MA, Morozov PV, Antipov AV, Vakhtomin YB, Smirnov KV. High-efficiency multi-element superconducting single-photon detector. In: Prochazka I, Štefaňák M, Sobolewski R, Gábris A, editors. Proc. SPIE. Vol 11771. SPIE; 2021. p. 2–8. 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.

	Moshkova MA, Divochiy AV, Morozov PV, Antipov AV, Vakhtomin YB, Smirnov KV. Characterization of topologies of superconducting photon number resolving detectors. In: Proc. 8th Int. Conf. Photonics and Information Optics.; 2019. p. 465–6. 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.
