Strong suppression of the resistivity near the transition to superconductivity in narrow micro-bridges in external magnetic fields
Xiaofu Zhang, Adriana E. Lita, Konstantin Smirnov +5
We have investigated a series of superconducting bridges based on homogeneous amorphous WSi and MoSi films, with bridge widths w ranging from 2 um to 1000 um and film thicknesses d…
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…
Superconducting detector for visible and near-infrared quantum emitters
V. Vorobyov, A. Kazakov, V. Soshenko +11
Further development of quantum emitter based communication and sensing applications intrinsically depends on the availability of robust single-photon detectors. Here, we demonstrat…
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…
Superconducting single-photon detector made of MoSi film
Yu. P. Korneeva, M. Yu. Mikhailov, Yu. P. Pershin +8
We fabricated and characterised nanowire superconducting single-photon detectors (SSPDs) made of 4 nm thick amorphous MoSi films. At 1.7 K the best devices exhibit a de…
Single photonics at telecom wavelengths using nanowire superconducting detectors
C. Zinoni, B. Alloing, L. H. Li +7
Single photonic applications - such as quantum key distribution - rely on the transmission of single photons, and require the ultimate sensitivity that an optical detector can achi…
