Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Designing chiral organic small molecules for circularly polarized light detection via group theory

open access: yesInfoMat, EarlyView.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

open access: yesLaser &Photonics Reviews, EarlyView.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Decoupling confinement and chiral symmetry breaking: an explicit model

open access: yes, 1991
Using a covariant model of mesons developed previously, we obtain new numerical solutions for the light-quark sector, and show explicitly how the small mass of the pion emerges as a natural consequence of chiral-symmetry breaking.

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.
