Advances in polarization optics and integrated photonics require fundamentally new polarization‐managing strategies allowing for efficient generation and complete control over vectorial fields with well‐defined polarization states using surface‐confined configurations with ultracompact footprints and extended bandwidths. Recently, metasurfaces have been extensively explored to demonstrate compact planar devices enabling diverse polarization control. However, the main drawback of the state‐of‐the‐art metasurface‐based polarization converters is related to their limitations resulting in individual simple functionalities and low‐efficiencies. Here, the strategy for producing dielectric metasurfaces that efficiently generate diversified polarization states with controllable wavefronts and high efficiencies over a broadband spectrum range from a linearly‐polarized light source by generalizing an existing theory of simultaneous phase and polarization control with birefringent meta‐atoms, is demonstrated. Advanced polarization and wavefront manipulation functionalized to realize an efficient polarization‐resolved multifocal metalens and vectorial holographic display is accomplished using judiciously designed dielectric metasurfaces composed of segmented sub‐arrays capable of manipulating, simultaneously and independently, both polarization and phase of the transmitted beams. The versatility of this concept provides opportunities to develop a complete set of flat polarization optics for integrated photonics and quantum optics.

使用介电超表面的多功能极化生成和操纵
偏振光学器件和集成光子学的进步要求从根本上采用新的偏振管理策略，以利用具有超紧凑封装和扩展带宽的表面受限配置，有效地生成和完全控制具有清晰偏振状态的矢量场。近来，已经广泛地探索了超颖表面，以证明紧凑的平面装置能够实现多种偏振控制。但是，最新的基于超表面的偏振转换器的主要缺点在于其局限性，导致其功能单一且效率低下。这里，通过推广现有的利用双折射亚原子同时进行相位和偏振控制的理论，论证了产生介电超表面的策略，该介电超表面有效地产生了可控波阵面并在宽带光谱范围内在宽带光谱范围内具有高效率的多样化偏振态。先进的偏振和波前操纵功能化，可以实现有效的偏振分辨多焦点金属元和矢量全息显示，它是通过精心设计的介电超表面来完成的，该介电超表面由分段的子阵列组成，能够同时且独立地操纵透射光束的偏振和相位。
