在基于超表面的超紧凑图像显示器中,彩色纳米打印、灰度成像元件和二进制图案成像元件是三种不同类型的纳米打印,其利用不同的光操纵机制来实现。在这里,我们展示了这三个功能元件可以集成在一起,形成一个“三合一”的纳米印刷品,可以忽略不计的串扰,仅仅是一个单细胞的纳米结构的设计方法。具体地说,通过解耦光谱和偏振辅助强度操纵的入射光,所提出的超颖表面出现作为一个双色纳米印刷在宽带非偏振光光源照明下,同时显示一个独立的连续灰度图像和另一个二进制图案在正交偏振光学设置与不同的偏振控制。我们的方法可以提高系统的集成度和安全性的元表面,这可能是感兴趣的许多先进的应用,如数据存储,光学信息编码,高端光学防伪,光学信息隐藏。将三种类型的纳米打印合并到一个具有可忽略串扰的超颖表面中提出了单细胞纳米结构设计方法光学;应用物理学;工程
In metasurface-based ultra-compact image display, color-nanoprints, gray-imaging elements, and binary-pattern-imaging elements are three different types of nanoprints, implemented with different mechanisms of light manipulation. Here, we show the three functional elements can be integrated together to form a “three-in-one” nanoprint with negligible crosstalk, merely with a single-cell nanostructured design approach. Specifically, by decoupling spectrum and polarization-assisted intensity manipulations of incident light, the proposed metasurface appears as a dual-color nanoprint under a broadband unpolarized light source illumination, while simultaneously displaying an independent continuous gray image and another binary-pattern in an orthogonal-polarization optical setup with different polarization controls. Our approach can increase the system integration and security of metasurfaces, which can be of interest to many advanced applications such as data storage, optical information encoding, high-end optical anti-counterfeiting, and optical information hiding.
