Abstract

Metasurface-based nanoprinting (meta-nanoprinting) has fully demonstrated its advantages in ultrahigh-density gray-scale/color image recording and display. A typical meta-nanoprinting device usually has image resolutions reaching 80 k dots per inch (dpi), far exceeding conventional technology such as gravure printing (typ. 5 k dpi). Besides, by fully exploiting the design degrees of freedom of nanostructured metasurfaces, meta-nanoprinting has been developed from previous single-channel to multiple-channels, to current multifunctional integration or even dynamic display. In this review, we overview the development of meta-nanoprinting, including the physics of nanoprinting to manipulate optical amplitude and spectrum, single-functional meta-nanoprinting, multichannel meta-nanoprinting, dynamic meta-nanoprinting and multifunctional metasurface integrating nanoprinting with holography or metalens, etc. Applications of meta-nanoprinting such as image display, vortex beam generation, information decoding and hiding, information encryption, high-density optical storage and optical anti-counterfeiting have also been discussed. Finally, we conclude the opportunities and challenges/perspectives in this rapidly developing research field of meta-nanoprinting.
超表面纳米打印:原理、设计与进展
基于超表面的纳米打印技术(meta-nanoprinting)在超高密度灰度/彩色图像记录和显示方面的优势已得到充分展示。典型的元纳米印刷设备通常具有达到每英寸80k点(dpi)的图像分辨率,远远超过凹版印刷(类型)等传统技术。5kdpi)。此外,通过充分利用纳米结构超表面的设计自由度,元纳米打印已经从以前的单通道发展到多通道,再到现在的多功能集成甚至动态显示。本文综述了纳米元打印技术的研究进展,包括控制光学振幅和光谱的纳米元打印、单功能纳米元打印、多通道纳米元打印、动态纳米元打印以及与全息或超透镜相结合的多功能纳米元打印等。讨论了元纳米印刷在图像显示、涡旋光束产生、信息解码与隐藏、信息加密、高密度光存储、光学防伪等方面的应用。最后,我们总结了这个快速发展的研究领域的机遇和挑战/前景。
