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…
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…
A superconducting NbN detector for neutral nanoparticles
M. Marksteiner, A. Divochiy, M. Sclafani +6
We present a proof-of-principle study of superconducting single photon detectors (SSPD) for the detection of individual neutral molecules/nanoparticles at low energies. The new det…
Sensitivity of a superconducting nanowire detector for single ions at low energy
M. Sclafani, M. Marksteiner, F. McLennar Keir +5
We report on the characterization of a superconducting nanowire detector for ions at low kinetic energies. We measure the absolute single particle detection efficiency and trac…
Superconducting parallel nanowire detector with photon number resolving functionality
F. Marsili, D. Bitauld, A. Fiore +9
We present a new photon number resolving detector (PNR), the Parallel Nanowire Detector (PND), which uses spatial multiplexing on a subwavelength scale to provide a single electric…
Superconducting nanowire photon number resolving detector at telecom wavelength
Aleksander Divochiy, Francesco Marsili, David Bitauld +12
The optical-to-electrical conversion, which is the basis of optical detectors, can be linear or nonlinear. When high sensitivities are needed single-photon detectors (SPDs) are use…
