Polarization-multiplexed spatial filtering in a symmetric TiO 2 metasurface with an anisotropic van der Waals gap fill

Year: 2026

Type: article

Abstract: with the crystal axes assigned as they lie in an exfoliated flake. A control series with isotropic and uniaxial gap fillings indicates that the shape anisotropy of the bar pair sets the scale of the channel separation, that the anisotropy of the crystal acts mainly through its out-of-plane index contrast, and that the in-plane birefringence contributes a small part of it.
