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…
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…
Polarization mode hybridization and conversion in phononic wire waveguides
Zhen Shen, Wei Fu, Ri-Sheng Cheng +3
Phononic wire waveguides of subwavelength cross-section support two orthogonal polarization modes: the out-of-plane motion dominated Rayleigh-like and the in-plane motion dominated…
Broadband on-chip single-photon spectrometer
Risheng Cheng, Chang-Ling Zou, Xiang Guo +3
Single-photon counters are single-pixel binary devices that click upon the absorption of a photon but obscure its spectral information, whereas resolving the colour of detected pho…
