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…
Cavity piezo-mechanics for superconducting-nanophotonic quantum interface
Xu Han, Wei Fu, Changchun Zhong +8
Hybrid quantum systems are essential for the realization of distributed quantum networks. In particular, piezo-mechanics operating at typical superconducting qubit frequencies feat…
Negative Refraction with High Transmission in Graphene-hBN Hyper Crystal
Ayed Al Sayem, Mahdy Rahman Chowdhury Mahdy, Ifat Jahangir +1
In this article, we have theoretically investigated the performance of graphene-hexagonal Boron Nitride hyper crystals to demonstrate all angle negative refraction.Hexagonal Boron…
Ultrathin Ultra-broadband Electro-Absorption Modulator based on Few-layer Graphene based Anisotropic Metamaterial
Ayed Al Sayem, Mahdy Rahman Chowdhury Mahdy, Ifat Jahangir +1
In this article, a few-layered graphene-dielectric multilayer (metamaterial) electro-optic modulator has been proposed in the mid and far infrared range that works on electro-absor…
