Excitation of Quasi‐Bound States in the Continuum With Focused Radially Polarized Beams

Advanced Optical Materials, EarlyView.
This work presents an innovative strategy for exciting symmetry‐protected quasi‐bound states in the continuum in periodic arrays of nanostructures using focused radially polarized light beams. Compared to excitation with a tilted plane wave, this approach can achieve both higher quality factors and stronger optical responses.

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms

Advanced Optical Materials, EarlyView.
This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.

Wrinkle‐Template Confinement of Kinetically Arrested Cellulose Nanocrystals for Sustainable Large Scale Reflection Gratings

Advanced Optical Materials, EarlyView.
Self‐supported all‐cellulose reflective gratings are fabricated from cellulose nanocrystal dispersions via a confinement printing process. Taking advantage of the reduced fluidity of concentrated, kinetically arrested cellulose nanocrystal dispersions, line arrays can be successfully transferred to dried CNC films.

The Role of Porosity in SERS

Advanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique
