Non-Hermitian Light Beams
Andrey Novitsky, Dongliang Gao, Iryna Kaputskaya +4
Non-Hermitian systems provide remarkable features actively studied in modern photonics. Non-Hermiticity is often related to the properties of open structures and devices, which inv…
General and concise operator approach to the dyadic Green's function of layered media
Aliaksandr Arlouski, Lei Gao, Dongliang Gao +1
Dyadic Green's function is an important tool of computational photonics, giving deeper insights into light-matter interaction. We present an operator approach to the derivation of…
Direct observation of photonic spin Hall effect in Mie scattering
Aizaz Khan, Nikolay Solodovchenko, Dongliang Gao +10
The photonic spin Hall effect (PSHE), a hallmark of spin-orbit interaction of light, has long been considered a promising route toward spin-controlled functionalities in nanophoton…
Loss-free enhancement of photonic spin Hall shift by electromagnetically induced transparency
Kezhou Du, Aizaz Khan, Lei Gao +3
The photonic spin Hall effect (PSHE), a result of spin-orbit interaction, has attracted significant interest because of its fundamental importance and potential applications. Optic…
Generalized coherent wave control at dynamic interfaces
Youxiu Yu, Dongliang Gao, Yukun Yang +10
Coherent wave control is of key importance across a broad range of fields such as electromagnetics, photonics, and acoustics. It enables us to amplify or suppress the outgoing wave…
