Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities
A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

Stable and switchable $$\textrm{VO}_2$$ -based metasurfaces in the near-infrared region
Metasurfaces, with their remarkable ability to control electromagnetic beams, provide great prospects for optical systems. Recently, active metasurfaces have gained more attention compared to passive ones due to their tunable functionality. However, most

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement
The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐

An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype
