Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

open access: yesAdvanced Optical Materials, EarlyView.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Geometry‐Driven Whispering‐Gallery Modes in Self‐Assembled Phosphorescent Organic Microtubes

open access: yesAdvanced Optical Materials, EarlyView.
Micelles encapsulating tris(2‐phenylpyridine)iridium(III) self‐assemble into a hollow hexagonal microtube stabilized by a surface passivation layer. The hexagonal cross‐section confines circulating light along its facets, sustaining sharp whispering‐gallery resonances that guide photoluminescence emission under laser excitation.

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Purely Equatorial Lasing in Spherical Liquid Crystal Polymer Microlasers with Bipolar Refractive Index Profile

open access: yesAdvanced Optical Materials, EarlyView.
Spherical liquid crystal polymer microlasers with a bipolar configuration confine lasing to a single equatorial plane, allowing precise control over where the laser emission is generated. The anisotropic refractive index profile additionally lifts the energy degeneracy of azimuthal whispering gallery modes, which causes a characteristic splitting into ...
