Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement

Advanced Materials, EarlyView.
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 ...

High-Performance and Fabrication-Tolerant 3 dB Adiabatic Coupler Based on Ultralow-Loss Silicon Waveguide by Tri-Layer Hard Mask Etching Process

Nanomaterials
Silicon photonics has emerged as critical for advancing photonic integrated circuits (PICs), but waveguide losses, primarily resulting from sidewall roughness, remain a primary challenge. In this work, we demonstrate a tri-layer hard mask etching process

Self‐Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Axial Heterostructures Grown by Molecular Beam Epitaxy

Advanced Materials Interfaces, EarlyView.
Following the parameter modulation described in the manuscript, a high yield of branch‐free self‐catalyzed AlGaAs nanowires at various nominal Al contents with high material quality has been acquired. These branchless structures are ideal hosts for narrower bandgap GaAs quantum dots, promising for non‐classical light‐emitting applications.

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
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‐

Nature‐Inspired Functional Aerogel Fibers with Engineerable Core–Shell Morphology

Advanced Materials Technologies, EarlyView.
Nature‐inspired core–shell aerogel fibers are fabricated through coaxial wet‐spinning, which combines a polyimide shell with MXene core. The fibers exhibited absorption‐dominant EMI shielding, low thermal conductivity, and mechanical robustness, demonstrating multifunctional potential for wearable electronics and advanced smart textiles.
