Planar chiral metasurfaces with maximal tunable chiroptical response driven by bound states in the continuum
Tan Shi, Zi-Lan Deng, Guangzhou Geng +8
Optical metasurfaces with high-Q chiral resonances can boost light-matter interaction for various applications of chiral response for ultrathin, active, and nonlinear metadevices.…
Perfect diffraction metagratings supporting bound states in the continuum and exceptional points
Zi-Lan Deng, Feng-Jun Li, Huanan Li +2
Resonance coupling in non-Hermitian systems can lead to exotic features, such as bound states in the continuum (BICs) and exceptional points (EPs), which have been widely employed…
Cylindrical vector beams reveal radiationless anapole condition in a resonant state
Yudong Lu, Yi Xu, Xu Ouyang +4
Nonscattering optical anapole condition is corresponding to the excitation of radiationless field distributions in open resonators, which offers new degrees of freedom for tailorin…
Near-perfect fidelity polarization-encoded multilayer optical data storage based on aligned gold nanorods
Linwei Zhu, Yaoyu Cao, Qiuqun Chen +5
Encoding information in light polarization is of great importance in facilitating optical data storage (ODS) for information security and data storage capacity escalation. However,…
Observation of Topologically Robust Localized Magnetic Plasmon Skyrmions
Zi-Lan Deng, Tan Shi, Alex Krasnok +2
Optical skyrmions have recently been constructed by tailoring electric or spin field distributions through the interference of multiple surface plasmon polaritons, offering promisi…
