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…
Incorporation of erbium ions into thin-film lithium niobate integrated photonics
Sihao Wang, Likai Yang, Risheng Cheng +5
As an active material with favorable linear and nonlinear optical properties, thin-film lithium niobate has demonstrated its potential in integrated photonics. Integration with rar…
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…
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…
