Abstract

Metasurfaces show an extraordinary ability for polarization control, despite the limitations imposed by their working bandwidth and complex meta-atom designs. Here, we present a strategy for generating arbitrary polarization in the broadband, relying solely on the Pancharatnam–Berry phase. The proposed metasurface design comprises two metamolecules arranged in a staggered configuration. Importantly, the orientation of the two metamolecules provides a new degree of freedom to control both the amplitude and phase of right- and left-circular polarization components. We experimentally demonstrated that the polarization of the scattered light can cover the entire Poincaré sphere by merely tuning the metamolecule orientation. These results provide a unique approach for fabricating ultracompact photonic devices and integrated quantum optical systems.

利用超分子交错排列的宽带全偏振控制

尽管受到工作带宽和复杂元原子设计的限制，超表面显示出非凡的极化控制能力。在这里，我们提出了一种在宽带中产生任意极化的策略，仅依赖于Pancharatnam-Berry相位。所提出的超表面设计包括以交错配置排列的两个超分子。重要的是，这两个超分子的取向为控制左右圆偏振分量的振幅和相位提供了新的自由度。我们通过实验证明，散射光的偏振只需要调整超分子的取向就可以覆盖整个庞加莱球。这些结果为制造超紧凑光子器件和集成量子光学系统提供了一种独特的方法。
