Thermal properties of NbN single-photon detectors
E. M. Baeva, M. V. Sidorova, A. A. Korneev +9
We investigate thermal properties of a NbN single-photon detector capable of unit internal detection efficiency. Using an independent calibration of the coupling losses we determin…
A single photon detection system for visible and infrared spectrum range
Alexander Divochiy, Marta Misiaszek, Yury Vakhtomin +4
We demonstrate niobium nitride based superconducting single-photon detectors sensitive in the spectral range 452 nm - 2300 nm. The system performance was tested in a real-life expe…
Superconducting single-photon detectors with saturated dependence of quantum efficiency vs. bias current
Konstantin Smirnov, Alexander Divochiy, Yury Vakhtomin +4
It was investigated the possibility of creating NbN superconducting single-photon detectors with saturated dependence of quantum efficiency versus normalized bias current. It was s…
Rise times of voltage pulses in NbN superconducting single-photon detectors
K. V. Smirnov, A. V. Divochiy, Yu. B. Vakhtomin +6
We have found experimentally that the rise times of voltage pulses in NbN superconducting single photon detectors increase nonlinearly with increasing detector length. We fabricate…
Superconducting detector of IR single-photons based on thin WSi films
V. A. Seleznev, A. Divochiy, Yu. B. Vakhtomin +6
We have developed the deposition technology of WSi thin films 4 to 9 nm thick with high temperature values of superconducting transition (Tc~4 K). Based on deposed films there were…
