Metasurfaces for quantum photonics [PDF]

open access: yesNature Photonics, 2021
Rapid progress in the development of metasurfaces allowed to replace bulky optical assemblies with thin nanostructured films, often called metasurfaces, opening a broad range of novel and superior applications to the generation, manipulation, and detection of light in classical optics.

Dynamic beam steering with all-dielectric electro-optic III–V multiple-quantum-well metasurfaces

open access: yesNature Communications, 2019
Here, the authors demonstrate an electrically tunable metasurface with III–V semiconducting MQW structures as resonant metasurface elements. The amplitude and phase of the light reflected from the metasurface can be continuously tuned by applying DC ...

Broadband High-Order OAM Reflective Metasurface With High Mode Purity Using Subwavelength Element and Circular Aperture

open access: yesIEEE Access, 2019
In this paper, high-order orbital angular momentum (OAM) vortex beams (OAMVBs) are generated using reflective metasurface. Generating high-order OAMVBs using traditional reflective metasurface methods deteriorates the radiation performance that affects ...

Highly Birefringent Terahertz Metasurfaces Based on a Liquid-Crystal-Embedded Metal Mesh

open access: yesIEEE Photonics Journal, 2022
Here, we report a metasurface for polarization converters in the terahertz (THz) spectral range. The THz metasurface consists of a metal mesh with subwavelength isotropic apertures and a nematic liquid crystal (LC) that is a uniaxially anisotropic ...

Information theory of metasurfaces [PDF]

open access: yesNational Science Review, 2019
Abstract We propose a theory to characterize the information and information processing abilities of metasurfaces, and demonstrate the relation between the information of the metasurface and its radiation pattern in the far-field region. By incorporating a general aperture model with uncertainty relation in L2-space, we propose a theory ...

Computational Analysis of Metasurfaces [PDF]

open access: yesIEEE Journal on Multiscale and Multiphysics Computational Techniques, 2018
Metasurfaces represent one of the most vibrant fields of modern science and technology. A metasurface is a complex electromagnetic structure, that is typically deeply subwavelength in thickness, electrically large in transverse size and composed of subwavelength scattering particles with extremely small features; it may generally be bianisotropic ...
