Journal of Synchrotron Radiation, EarlyView.This study presents systematic measurements and rigorous coupled‐wave analysis of relative and absolute diffraction efficiencies for sub‐15 nm soft X‐ray Fresnel zone plates. By decoupling intrinsic optical performance from practical beamline transmission losses, this work establishes a highly reliable metrology framework to support the development of ...

Guided-Mode Resonances in GaN Membrane Grating
IEEE Photonics Journal, 2014 This paper proposes guided-mode resonant GaN grating that are implemented on a GaN-on-silicon wafer structure. Numerical simulations based on rigorous coupled wave analysis (RCWA) are performed to model multiple resonances in thick GaN membranes.

Polarization-Independent Two-Layer Grating With Five-Port Splitting Output Under Normal Incidence
IEEE Photonics Journal, 2020 In this paper, we report a two-layer five-port diffraction grating by a polarization-independent design under normal incidence. To be different from conventional five-port gratings, initially, we design a novel two-layer grating with operation in ...

Extrinsic Limitations of Stealthy Hyperuniform Devices
Advanced Optical Materials, Volume 14, Issue 37, 9 October 2026.Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...

Band‐Pass to Band‐Stop Switchable Color Filters Based on Birefringent Dielectric Metasurfaces
Advanced Photonics Research, Volume 7, Issue 10, October 2026.Birefringent TiO2 metasurfaces enable a single nanostructure to operate as either a band‐pass or band‐stop color filter through simple rotation of an external polarizer. The all‐dielectric architecture combines high transmission efficiency with submicron pixel pitches, offering a compact and versatile approach to high‐resolution spectral filtering ...
