Paper Abstract

Metamaterials are artificially structured materials that have unconventional physical phenomena not found in nature materials. Metasurfaces, the two-dimensional equivalent of metamaterials, are periodic arrays of sub-wavelength engineered structures. Very recently, we have witnessed the rapid development of plasmonic and dielectric metasurfaces, which can enable flexible manipulation of structured light when meeting the structured metasurfaces. In this talk, we will review our recent research progress in plasmonic and dielectric metasurfaces on different platforms (metal, silicon, silica, fiber) for structured light manipulation: 1) broadband generation of orbital angular momentum (OAM) carrying vector beams using rectangular aperture array metasurfaces; 2) N-fold OAM multicasting using V-shaped antenna array metasurfaces; 3) design and fabrication of efficient reflective metasurfaces for the generation of OAM modes at 2 μm; 3) design and fabrication of metasurfaces on optical fiber facet for the generation of linearly polarized (LP) modes, linearly and circularly polarized OAM modes at 632.8 nm and 1550 nm; 4) design and fabrication of elliptical array all-dielectric metasurfaces for OAM modes generation and communications.
