Theory of Supercritical Coupling and Generalized Bound States in the Continuum

Laser &Photonics Reviews, EarlyView.
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

Macromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

Virtual Overlay Staining With Plasmonic Oligomer Metasurface

Small, EarlyView.
A scalable plasmonic metasurface enables “virtual staining” of living cells by enhancing optical contrast from refractive index differences. Through electrostatically assembled nanoparticle oligomers on a mirror, cellular components such as nuclei, mitochondria, and lipid‐rich regions are visualized without molecular dyes. This approach simplifies cell

Efficient Enantiomeric Selectivity Separation Via Homochiral Graphene Oxide Membrane

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
A new type of chiral graphene oxide (GO) membrane is proposed that exhibits a separation factor of up to 20.1 as well as a preferential enantiomer flux of 4.5 mmol m−2 h−1. Moreover, the only first FPLC‐compatible column has been further developed via stacking these chiral GO membranes.

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and
