Freestanding Polymer Metasurface Supporting Higher‐Order Optical Resonances for Strong Field Enhancement in TMD Monolayers

open access: yesSmall, Volume 22, Issue 35, 23 June 2026.
A freestanding polymer metasurface is developed to enhance light emission from atomically thin semiconductors. By supporting higher‐order optical resonances that concentrate electromagnetic fields at the surface, the platform significantly improves coupling between light and WS2 monolayer.

High‐Barrier Amorphous Al2O3 Film Deposited via Magnetic Field‐Confined for Ultrastable Hygroscopic Scintillators

open access: yesSmartMat, Volume 7, Issue 3, June 2026.
The moisture‐induced degradation of hygroscopic scintillators limits their performance and lifespan in radiation detection. A 100 nm amorphous Al2O3 film, deposited at room temperature via FCVA with pulsed magnetic field confinement, offers high optical transmittance and ultralow moisture permeability.

Theoretical analysis and experiment of subwavelength structure-integrated red AlGaInP light-emitting diodes for uniform field distribution and enhanced light extraction efficiency

open access: yesAIP Advances, 2016
We report theoretical and experimental analysis of antireflective subwavelength structures (SWSs) on GaP substrates to enhance the light output with a uniform light distribution of AlGaInP-based red light-emitting diodes (LEDs).

Metrology of optically-unresolved features using interferometric surface profiling and RCWA modeling

open access: yesOptics Express, 2008
Rigorous coupled wave analysis (RCWA) interprets 3D white-light interference microscopy profiles and reveals the dimensions of optically-unresolved surface features. Measurements of silicon etch depth of a 450-nm pitch grating structure correlate to atomic force microscopy with R(2)= 0.995 and a repeatability of 0.11nm. This same technique achieves a

Numerical Estimation of Bending in Holographic Volume Gratings by Means of RCWA and Deep Learning

open access: yesApplied Sciences
In this paper, we introduce a novel approach to model bending phenomena on holographic volume gratings based on Rigorous Coupled Wave Analysis (RCWA), in which the bending as a phase in the dielectric permittivity expansion is introduced, and the ...

Sensitivity of a Label-Free Guided-Mode Resonant Optical Biosensor with Different Modes

open access: yesSensors, 2012
Sensitivity is a key factor in the performance of a sensor. To achieve maximum guided-mode resonant optical biosensor sensitivity, a comparison of biosensor sensitivity for Transverse Electric (TE) and Transverse Magnetic (TM) modes based on the ...
