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…
Bidirectional electro-optic conversion reaching 1% efficiency with thin-film lithium niobate
Yuntao Xu, Ayed Al Sayem, Linran Fan +7
Superconducting cavity electro-optics (EO) presents a promising route to coherently convert microwave and optical photons and distribute quantum entanglement between superconductin…
Mitigating photorefractive effect in thin-filmlithium niobate microring resonators
Yuntao Xu, Mohan Shen, Juanjuan Lu +3
Thin-film lithium niobate is an attractive integrated photonics platform due to its low optical loss and favorable optical nonlinear and electro-optic properties. However, in appli…
Photorefraction-induced Bragg scattering in cryogenic lithium niobate ring resonators
Yuntao Xu, Ayed Al Sayem, Chang-Ling Zou +2
We report intracavity Bragg scattering induced by photorefractive (PR) effect in high-Q lithium niobate (LN) ring resonators at cryogenic temperatures. We show that, when a cavity…
Stable tuning of photorefractive micro-cavities using an auxiliary laser
Joshua B. Surya, Juanjuan Lu, Yuntao Xu +1
Cavity nonlinear optics enables intriguing physical phenomena to occur at micro- or nano-scales with modest input powers. While this enhances capabilities in applications such as c…
Ground-state Pulsed Cavity Electro-optics for Microwave-to-optical Conversion
Wei Fu, Mingrui Xu, Xianwen Liu +9
In the development of quantum microwave-to-optical (MO) converters, excessive noise induced by the parametric optical drive remains a major challenge at milli-Kelvin temperatures.…
