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…
Tunable telecom to mid-infrared optical parametric oscillation via microring-based nonlinearities
Yulong Tang, Zheng Gong, Xiangwen Liu +1
Optical parametric oscillation (OPO) with far-shifted frequency sidebands has attracted significant interests in precision spectroscopy and quantum information processing. Microres…
Magnon-photon strong coupling for tunable microwave circulators
Na Zhu, Xu Han, Chang-Ling Zou +2
We present a generic theoretical framework to describe non-reciprocal microwave circulation in a multimode cavity magnonic system and assess the optimal performance of practical ci…
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…
