Integration of superconducting nanowire single-photon detectors with nanophotonic
waveguides is a key technological step that enables a broad range of classical and quantum …

Two decades after their demonstration, superconducting nanowire single-photon detectors
(SNSPDs) have become indispensable tools for quantum photonics as well as for many …

In recent years, photon-number-resolving (PNR) detectors have attracted great interest,
mainly because they can play a key role in diverse application fields. A PNR detector with a …

Single-photon detectors at near-infrared wavelengths with high system detection efficiency
(> 90%), low dark count rate (< 1 cps), low timing jitter (< 100 ps) and short reset time (< 100 …

Using a kinetic-equation approach, we study the dynamics of electrons and phonons in
current-carrying superconducting nanostrips after the absorption of a single photon of the …

In this paper we intend to give a comprehensive description of the current understanding of
the detection mechanism in superconducting nanowire single-photon detectors. We will …

We demonstrate experimentally that the critical current in superconducting NbTiN wires is
dependent on their geometrical shape, due to current-crowding effects. Geometric patterns …

We report an experimental test of the photodetection mechanism in a nanowire
superconducting single photon detector. Detector tomography allows us to explore the 0.8–8 …

Superconducting nanostrip photon detectors have been used as single-photon detectors,
which can discriminate only photons' presence or absence. It has recently been found that …

The photon count rate (PCR) of superconducting single-photon detectors made of Mo x Si 1-
x films shaped as a 2-μ m-wide strip and a 115-nm-wide meander strip line is studied …
