Superconducting Nanowire Single-Photon Detector (SNSPD) with 3D-Printed Free-Form Microlenses
Yilin Xu, Artem Kuzmin, Emanuel Knehr +6
We present an approach to increase the effective light-receiving area of superconducting nanowire single-photon detectors (SNSPD) by means of free-form microlenses that are printed…

Synchronous single-photon detection with self-resetting GHz-gated superconducting NbN nanowires
Emanuel Knehr, Artem Kuzmin, Steffen Doerner +4
We demonstrate a GHz-gated operation of resonator-coupled superconducting nanowire single-photon detectors suitable for synchronous applications. In comparison with conventional dc…

Nanowire single-photon detectors made of atomic layer-deposited niobium nitride
Emanuel Knehr, Artem Kuzmin, Mario Ziegler +5
We demonstrate and characterize first superconducting nanowire single-photon detectors (SNSPDs) made from atomic layer-deposited (ALD) NbN layers. To assess the suitability of thes…
