Nonlinear Imaging with All-Dielectric Metasurfaces
Nano Letters, 2020 Nonlinear metasurfaces incorporate many of the functionalities of their linear counterparts such as wavefront shaping but simultaneously they perform nonlinear optical transformations. This dual functionality leads to a rather unintuitive physical behavior which is still widely unexplored for many photonic applications.

Effects of roughness and resonant-mode engineering in all-dielectric metasurfaces
Nanophotonics, 2020 The development of all-dielectric metasurfaces vigorously prompts the applications of optical metasurfaces for the visible and near-IR light range. Compared to IR or longer wavelength light, visible and near-IR light have shorter wavelengths. As a result,

All-dielectric bianisotropic metasurfaces [PDF]
2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS), 2016 Bianisotropic all-dielectric metasurfaces are demonstrated experimentally and their properties are studied in the microwave frequency range. Such metasurfaces are composed of dielectric particles with broken symmetry that exhibit different backscattering for the opposite excitation directions.

Shape dependence of all-dielectric terahertz metasurface
Optics Express, 2022 All-dielectric metasurfaces have been attracting attention in the terahertz spectral range for low-loss planar optical elements such as lenses, beam splitters, waveplates, vortex plates, and magnetic mirrors. Various shapes of meta-atoms have been used in many studies; however, no systematic comparative study of each shape has been reported.

Genetically optimized all-dielectric metasurfaces
Optics Express, 2017 We present and study theoretically a new design approach for obtaining wide angle, highly efficient, all-dielectric metasurfaces. As a concrete example we focus on optimizing flat beam deflector for both the infra-red and visible spectral regions. Transmission efficiencies of up to 87.2% are obtained theoretically for deflection angle of 65° in visible
