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 ...

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 ...

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 ...

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

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 ...

Nanophotonics, Volume 15, Issue 18, 25 September 2026.Here, we report a single‐band guided‐mode resonance (GMR) InGaAs photodetector (PD) array. The device consists of an InGaAs PD with an ultrathin absorption layer bonded onto a Si 2D grating. Although a 2D crossed‐grating inherently supports many more optical modes than a 1D grating, we realized a single‐band response by introducing novel design ...
