Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator

Laser &Photonics Reviews, EarlyView.
This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐

Symmetric Metal Organic Framework‐Plasmonic Architectures for Reversible and High‐Sensitivity Optical Sensing

Small, EarlyView.
This work presents a plasmonic sensing platform combining surface lattice resonances (SLRs) in 2D metal nanoparticle gratings with ZIF‐8 MOF films. The plasmonic grating is easily and scalably produced from template‐assisted assembly of metal colloids, which is fully compatible with MOF growth. The resulting MOF‐plasmonic structure allows for a dynamic

Conundrums of Localized Surface Plasmon Resonance Biosensors

Small, EarlyView.
Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

Small Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...
