Deterministic Fractal Plasmonic Metasurfaces for Broadband Mid‐Infrared Molecular Biosensing
Advanced Photonics Research, Volume 7, Issue 9, September 2026.This image illustrates a sensing platform based on deterministic fractal plasmonic metasurfaces, designed to overcome the persistent trade‐off between sensitivity and spectral bandwidth in surface‐enhanced infrared absorption (SEIRA) spectroscopy. At the heart of the schematic is a hierarchical subwavelength gold aperture array featuring self‐similar ...

Advanced Photonics Research, Volume 7, Issue 9, September 2026.A gold substrate with an HSQ‐filled C‐shaped engraving selectively pushes a plasmonic nanoparticle from a three‐particle cluster toward its center, leaving dielectric and chiral neighbors nearly unaffected. Validated against published results, a coupled electromagnetic‐thermal analysis confirms this optical force exceeds competing thermophoretic ...

Layer‐Dependent Phonon Polaritons in hBN Resolved by Photo‐Induced Force Spectroscopy
Advanced Science, Volume 13, Issue 50, 7 September 2026.Layer‐dependent phonon polariton resonances in hexagonal boron nitride are systematically investigated using photo‐induced force microscopy. The in‐plane resonance exhibits a blueshift, while the out‐of‐plane resonance shows a redshift with increasing thickness. These results establish layer number as a key parameter for tuning polaritonic responses in

Advanced Science, Volume 13, Issue 51, 14 September 2026.Dynamic microcavities provide reversible control over exciton‐photon coupling in two‐dimensional TMDs through piezoelectric, electrical, thermal, and all‐optical tuning. By reshaping detuning, Rabi splitting, and polariton composition, these strategies enable adaptable polaritonic functions, including optical switching, polariton lasing, and ...

Advanced Electronic Materials, Volume 12, Issue 18, 21 September 2026.An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...

Optical tunneling effect of surface plasmon polaritons and localized surface plasmon resonance
, 2002 Surface plasmon resonance of periodic narrow-grooved metallic thin films were studied with finitedifference time-domain simulations. Two distinguishable modes, surface plasmon polaritons and localized surface plasmons, are associated with different ...
