Optical metasurfaces enable novel ways to locally manipulate light's amplitude, phase, and polarization, underpinning a newly viable technology for applications, such as high-density optical storage, holography, and displays. Here, a high-security-level platform enabled by centimeter-scale plasmonic metasurfaces with full-color, high-purity, and enhanced-information-capacity properties is proposed. Multiple types of independent information can be embedded into a single metamark using full parameters of light, including amplitude, phase, and polarization. Under incoherent white light, the metamark appears as a polarization- and angle-encoded full-color image with flexibly controlled hue, saturation, and brightness, while switching to multiwavelength holograms under coherent laser illumination. More importantly, for actual applications, the extremely shallow functional layer makes such centimeter-scale plasmonic metamarks suitable for cost-effective mass production processes. Considering these superior performances of the presented multifunctional plasmonic metasurfaces, this work may find wide applications in anticounterfeiting, information security, high-density optical storage, and so forth.

通过厘米级等离子超颖表面同时进行全色打印和全息照相。

光学超表面提供了新颖的方法来本地控制光的振幅，相位和偏振，从而为诸如高密度光学存储，全息和显示器之类的应用提供了一种新的可行技术。在此，提出了一种具有厘米级等离子超表面的，具有全色，高纯度和增强的信息容量特性的高安全性平台。可以使用光的完整参数（包括幅度，相位和偏振）将多种类型的独立信息嵌入到单个metamark中。在不相干的白光下，元标记显示为偏振和角度编码的全色图像，具有可灵活控制的色相，饱和度和亮度，而在相干激光照射下切换为多波长全息图。更重要的是，对于实际应用，极浅的功能层使这种厘米级的等离子元标记适合经济高效的批量生产过程。考虑到所提出的多功能等离子超表面的这些优越性能，这项工作可能会在防伪，信息安全，高密度光存储等方面获得广泛的应用。
