Operation of a Superconducting Nanowire in Two Detection Modes: KID and SPD by Schroeder, Edward, Mauskopf, Philip, Mani, Hamdi, Bryan, Sean, Berggren, Karl K., Zhu, Di

“…We present the performance of a superconducting nanowire that can be operated in two detection modes: (i) as a kinetic inductance detector (KID) or (ii) as a single-photon detector (SPD). Two superconducting nanowires developed for use as single-photon detectors (SNSPDs) are embedded as the inductive (L) component in resonant inductor/capacitor (LC) circuits coupled to a microwave transmission line. …”

High-uniformity atomic layer deposition of superconducting niobium nitride thin films for quantum photonic integration by C T Lennon, Y Shu, J C Brennan, D K Namburi, V Varghese, D T Hemakumara, L A Longchar, S Srinath, R H Hadfield

“…We report on the growth of highly uniform superconducting NbN thin films via plasma-enhanced atomic layer deposition (PEALD) with radio frequency substrate biasing, on a 200 mm (8 inch) Si wafer, specifically for superconducting nanowire single-photon detector applications. Niobium nitride films were grown using (tert-butylimido)-tris(diethylamido)-niobium(V) precursor and an H _2 /Ar plasma. …”

Cryogenic phonon-scintillation detectors with PMT readout for rare event search experiments and characterisation of a PMT at milli-Kelvin temperatures by Lin, J

“…The PMT is demonstrated to have low dark count rate and high gain at milli-Kelvin temperatures, thus it remains an effective single photon detector. From the radioactivity of a similar model of PMT as input to a Geant4 simulation, the radioactivity introduced by the PMT contributes only minorly (<10%) to the overall radioactive background of a hypothetical CPSD module for WIMP searches. …”

Scenario-based uncertainty quantification for deep space optical communications by Milton, Julia

Timing performance of 30-nm-wide superconducting nanowire avalanche photodetectors by Najafi, Faraz, Marsili, Francesco, Dauler, Eric A., Molnar, Richard J., Berggren, Karl K.

“…We investigated the timing jitter of superconducting nanowire avalanche photodetectors (SNAPs, also referred to as cascade-switching superconducting single-photon detectors) based on 30-nm-wide nanowires. At bias currents (I[subscript B]) near the switching current, SNAPs showed sub-35-ps FWHM Gaussian jitter similar to standard 100-nm-wide superconducting nanowire single-photon detectors. …”
