摘要
计算全息术与纳米印刷术是超表面材料的两种典型应用。近年来,融合全息术与纳米印刷术的多功能超表面成为新兴研究热点,有望在多重光学防伪、信息编码与复用、多通道图像显示、VR/AR等领域得到重要应用。文中在介绍超表面纳米印刷术和计算全息术特点的基础上,将实现两者融合的研究进展进行了详细的归类和特点分析,具体包括:正交偏振复用法、平面合成法、空间堆叠法、光谱+相位调控法、复振幅法、转角简并性法等。最后,对多功能超表面的研究前景进行了展望。
Computer-generated holography and nanoprinting are two typical applications of optical metasurfaces.Recently,merging holography and nanoprinting into a multifunctional metasurface becomes an emerging research hotspot,which has prospective applications in multi-folded anti-counterfeiting,information decoding and multiplexing,multi-channel image display and VR/AR,etc.In this paper,based on the features of metasurface-based nanoprinting and computer-generated holography,the advances in the research of merging them were classified and characterized in detail.Specifically,the merging methods were discussed in detail which included orthogonal-polarization multiplexing scheme,in-plane arrangement scheme,multilayer-stacking scheme,simultaneous spectrum and phase control scheme,complex amplitude modulation scheme,orientation degeneracy scheme.The future development of multifunctional metasurfaces was prospected.
