Light-induced dynamic frequency shifting of microwave photons in a superconducting electro-optic converter
Yuntao Xu, Wei Fu, Yiyu Zhou +4
Hybrid superconducting-photonic microresonators are a promising platform for realizing microwave-to-optical transduction. However, the absorption of scattered photons by the superc…
Superconducting cavity piezo-electromechanics: the realization of an acoustic frequency comb at microwave frequencies
Xu Han, Chang-Ling Zou, Wei Fu +3
We present a nonlinear multimode superconducting electroacoustic system, where the interplay between superconducting kinetic inductance and piezoelectric strong coupling establishe…
III-Nitride nanophotonics for beyond-octave soliton generation and self-referencing
Xianwen Liu, Zheng Gong, Alexander W. Bruch +3
Frequency microcombs, successors to mode-locked laser and fiber combs, enable miniature rulers of light for applications including precision metrology, molecular fingerprinting, an…
Epitaxial niobium nitride superconducting nanowire single-photon detectors
Risheng Cheng, John Wright, Huili G. Xing +2
Superconducting nanowires used in single-photon detectors have been realized on amorphous or poly-crystalline films. Here, we report the use of single-crystalline NbN thin films fo…
High-acoustic-index-contrast phononic circuits: numerical modeling
Wance Wang, Mohan Shen, Chang-Ling Zou +3
We numerically model key building blocks of a phononic integrated circuit that enable phonon routing in high-acoustic-index waveguides. Our particular focus is on Gallium Nitride-o…
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…
