Dirac-vortex modes beyond the continuum limit
Jiayu Fan, Jiusi Yu, Aoning Luo +7
Dirac-vortex modes (DVMs) in Kekule-modulated lattices provide a topological route to wave confinement and are commonly described by the continuum Jackiw-Rossi model, in which the…
Unveiling spin-orbital angular momentum locking in photonic Dirac vortex cavities
Haitao Li, Jiusi Yu, Jiayu Fan +6
Dirac vortices, originally studied in quantum field theories to predict localized zero-energy modes, were recently realized in photonics, leading to Dirac vortex cavities. With top…
Kirigami-based Flexible Metasurface with Reconfigurable Intrinsic Chirality from Zero to Near-unity
Yiyi Yao, Shijie Kang, Aoning Luo +7
Chiral responses in electromagnetic metasurfaces are typically categorized as extrinsic, resulting from asymmetric interactions between the structure and incident waves, and intrin…
Hybrid Cavity from Tunable Coupling between Anapole and Fabry-Perot Resonance or Anti-resonance
Aoning Luo, Haitao Li, Ken Qin +8
Enhancing light-matter interactions depends critically on the ability to tailor photonic modes at subwavelength scales, and combining distinct resonant modes has shown remarkable p…
Giant and Rapidly Switching Intrinsic Chirality Enabled by Toroidal Quasi-Bound States in the Continuum

Twist-enabled Transmissive Metasurface with Co-polarized Geometric Phase
Jiusi Yu, Haitao Li, Shijie Kang +6
Metasurfaces have offered unprecedented control over electromagnetic (EM) waves across a wide range of frequency spectrum by manipulating their phase, amplitude, and polarization a…
Nonlocal Generation of Fano Resonance with No Symmetry Breaking in THz Hybrid Metasurfaces
Boyuan Ge, Jiayu Fan, Ken Qin +4
Fano resonance, arising from the interference between a discrete resonance and a continuum of states, results in sharp and asymmetric line shapes and has significant applications i…
Giant and Flexible Toroidal Circular Dichroism from Planar Chiral Metasurface
Shijie Kang, Haitao Li, Jiayu Fan +4
Chirality, a fundamental concept describing an object cannot superpose with its mirror image, is crucial in optics and photonics and leads to various exotic phenomena, such as circ…
Multi-channel frequency router based on valley-Hall metacrystals
Jiayu Fan, Haitao Li, Shijie Kang +5
Topological photonics has revolutionized manipulations of electromagnetic waves by leveraging various topological phases proposed originally in condensed matters, leading to robust…
