Design of micron-long superconducting nanowire perfect absorber for efficient high speed single-photon detection
Risheng Cheng, Sihao Wang, Chang-Ling Zou +1
Despite very efficient superconducting nanowire single-photon detectors (SNSPDs) reported recently, combining their other performance advantages such as high speed and ultra-low ti…
Lithium-Niobate-on-Insulator Waveguide-Integrated Superconducting Nanowire Single-Photon Detectors
Ayed Al Sayem, Risheng Cheng, Sihao Wang +1
We demonstrate waveguide-integrated superconducting nanowire single-photon detectors on thin-film lithium niobate (LN). Using a 250 um-long NbN superconducting nanowire lithographi…
Active Quenching of Superconducting Nanowire Single Photon Detectors
Prasana Ravindran, Risheng Cheng, Hong Tang +1
Superconducting nanowire single photon detectors are typically biased using a constant current source and shunted in a conductance which is over an order of magnitude larger than t…
Superconducting nanowire single-photon detectors fabricated from atomic-layer-deposited NbN
Risheng Cheng, Sihao Wang, Hong X. Tang
High-quality ultra-thin films of niobium nitride (NbN) are developed by plasma-enhanced atomic layer deposition (PEALD) technique. Superconducting nanowire single-photon detectors…
Large-Area Superconducting Nanowire Single-Photon Detector with Double-Stage Avalanche Structure
Risheng Cheng, Menno Poot, Xiang Guo +2
We propose a novel design of superconducting nanowire avalanche photodetectors (SNAPs), which combines the advantages of multi-stage avalanche SNAPs to lower the avalanche current…
