Rigorous Electromagnetic Quasinormal‐Mode Method Made Easy for Users

Laser &Photonics Reviews, EarlyView.
We present a method that combines numerical techniques with accurate approximations to enable simple and ultrafast computations of the scattered field based on quasinormal modes expansions. The method is made available in the open‐source package MANlite (https://doi.org/10.5281/zenodo.18708748), implemented within COMSOL.

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

Au LSPR Effect Enhanced R‐CeO2/G‐C3N4 S‐scheme Heterojunction for Accelerating CO2 Photoreduction Performance

Small, EarlyView.
This study develops an Au localized surface plasmon resonance (LSPR) enhanced S‐scheme heterojunction between oxygen vacancy‐rich CeO2 (R‐CeO2) and graphitic carbon nitride (g‐C3N4) for efficient CO2 photoreduction. The ternary catalyst achieves high CO yield by synergistically improving carrier separation and reducing energy barriers, as validated ...

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 ...
