Decoupled Spectral Tuning and Polarization Locking in Twisted α $\alpha $‐MoO3 Polaritonic Crystals

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
We introduce a deterministic design strategy employing twisted bilayer α $\alpha $‐MoO3 ${\text{MoO}}_{3}$ polaritonic crystals to decouple infrared spectral and polarization degrees of freedom. Although adjusting the interlayer twist angle tunes the absorption spectra, the maximum absorption axis remains robustly locked to the patterned layer's ...

Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

Laser &Photonics Reviews, Volume 20, Issue 18, 18 September 2026.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Polarization-Independent Filter Based on 2-D Crossed Grating Under Oblique Incidence

IEEE Photonics Journal, 2018
The existing polarization-insensitive filters based on two dimensional (2-D) grating are mostly under normal incidence. However, in filtering optical devices, the normal incidence regime is usually avoided because it requires the use of beam separators ...

Physical properties of the tunic in the pinkish-brown salp Pegea confoederata (Tunicata: Thaliacea)

Zoological Letters, 2018
Background Invisibility in the water column is a crucial strategy for gelatinous zooplanktons in avoiding detection by visual predators, especially for animals distributed in the euphotic zone during the daytime; i.e., surface dwellers that do not ...

Accurate Structural Parameter Retrieval for One-Dimensional Nanogratings in Mueller-Matrix Spectroscopic Ellipsometry Using an Element-Adaptive Hybrid Surrogate Model

Applied Sciences
Mueller-matrix spectroscopic ellipsometry (MMSE) enables accurate characterization of nanostructures; however, structural-parameter retrieval remains challenging because of the high computational cost of rigorous coupled-wave analysis (RCWA), element ...

Modeling full PCSELs and VCSELs using modified rigorous coupled-wave analysis

An integrated rigorous coupled-wave analysis (RCWA) algorithm is presented in this paper, which can simulate full vertical-cavity surface-emitting laser (VCSEL) and photonic crystal surface-emitting laser (PCSEL) structures.

Mitigating the Impact of Asymmetric Deformation on Advanced Metrology for Photolithography

Applied Sciences
Controlling overlay in lithography is crucial for improving the yield of integrated circuit manufacturing. The process disturbances can cause undesirable morphology changes of overlay targets (such as asymmetric grating), which can significantly impact ...

Near-Field Lithography Optical Proximity Correction Based on Covariance Matrix Adaptation Evolution Strategy

Photonics
Near-field lithography (NFL) can achieve super-resolution patterning beyond the optical diffraction limit by using evanescent waves. However, optical proximity effects in NFL can lead to nonuniform near-field intensity distribution, reduced image ...
