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 polarization-dependent 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.

我们报告了一种由混合全介电纳米鳍组成的高效几何相位超表面，其中在可见光频率下获得了 93% 的转换效率。如此高的效率源于对极化相关奇偶校验的反铁磁共振模式的激励，即偶数和奇数的反平行磁偶极子将在传输场的两个正交分量之间引入π相位延迟。我们进一步证明了使用混合全介电超表面产生聚焦光学涡旋 (OV)、贝塞尔 OV 和自动聚焦艾里 OV，这在灵活的光捕获和光通信中显示出有前景的应用。
