Giant Enhancement of the Anomalous Transverse Magneto‐Optical Kerr Effect in a Magneto‐Optical Grating

open access: yesNanophotonics, Volume 15, Issue 10, 27 May 2026.
We demonstrate an indirect magneto‐optical coupling mechanism that overrides the symmetry‐induced suppression of s‐polarized TMOKE. A quasi‐two‐dimensional grating coordinates orthogonal resonances to establish a near‐zero reflection background and maximal near‐field asymmetry, achieving a theoretical‐limit TMOKE of ∼2.

Dual plasmonic modes in the visible light region in rectangular wave-shaped surface relief plasmonic gratings

open access: yesScientific Reports, 2023
Rectangular wave-shaped surface-relief plasmonic gratings (RSR-PGs) have been fabricated from a hybrid polymer by employing a simple nanoimprint photocuring lithography technique using a silicon template, followed by gold nanolayer metallization on top ...

Spectropolarimetric Holographic Multiplexing Metasurface With Super‐High Capacity Empowered by Mechanical Rotation

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Mechanically reconfigurable metasurfaces enable high‐capacity optical storage and holography due to low cost/complexity. A differentiable inverse design framework maps meta‐atom geometries to multichannel optical responses via deep neural networks. Rotatable cascaded metasurfaces optimized through this pipeline achieve pixel‐level holography with 288 ...

Polarization-Independent Two-Layer Grating With Five-Port Splitting Output Under Normal Incidence

open access: yesIEEE 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 ...

Ultrastable Photoactive Halide Perovskite Nanocrystal‐Sensitized SnO2 Nanorods for Room‐Temperature NO2 Detection

open access: yesAdvanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
ABSTRACT Metal oxide (MOx)‐based NO2 gas sensors typically require high temperatures or ultraviolet light, limiting their practical use. To enable visible‐light activation at room temperature, efficient and stable photosensitizers should be integrated with nanostructured MOx hosts.

Dual‐Symmetry Hybridization‐Controlled Plasmonic Bound States in the Continuum for Advanced Refractometric Sensing

open access: yesAdvanced Sensor Research, Volume 5, Issue 4, April 2026.
In plasmonic systems, quasi‐BICs are constrained by nonradiative losses, making radiative–absorptive balance essential. We analyze substrate‐induced hybridization in silver metasurfaces, showing that thickness relative to the skin depth yields three sensitivity regimes. Dual symmetry control tunes radiative and absorptive decay, optimizing coupling and

Diffraction grating theory with RCWA or the C method

open access: yes, 2006
Diffraction gratings are often used in optical metrology. When an electromagnetic wave is incident on a grating, the periodicity of the grating causes a multiplicity of diffraction orders.

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).

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 ...
