摘要：We report a high-efficiency geometric-phase metasurface composed of hybrid all-dielectric nanofins, of which the conversion efficiency 93% is obtained in visible frequency. Such high efficiency originates from the stimulation of the anti-ferromagnetic resonance modes of polarizationdependent parity, i.e. even and odd number of anti-parallel magnetic dipoles would introduce π phase delay among two orthogonal components of the transmitted field. We further demonstrate the generation of the focused optical vortex (OV), Bessel OV and autofocusing Airy OV with the hybrid all-dielectric metasurfaces, which shows promising applications in flexible optical trapping and optical communications.
