摘要:

光学超构表面传统上被视为由光子或等离激元纳米谐振器(也称为超原子)构成的规整平面阵列。这类超构表面通常高度有序,需借助昂贵设备精密制备。然而,大规模纳米光子器件中固有的缺陷,结合自下而上纳米制备技术与设计策略的最新进展,凸显了引入无序以实现特定光学功能的潜在优势。本综述概述了与无序光学超构表面研究相关的关键理论、数值与实验层面内容。文中介绍了无序超构表面光散射的基本概念,梳理了分析其光学行为的理论与数值方法;讨论了多种制备技术,重点说明其产生的无序类型及可达到的精度水平;还探讨了无序光学超构表面的重要应用,例如薄膜材料中的光调控、结构色与视觉外观设计。最后,文章对该领域新兴的未来研究方向给出了展望。无序光学超构表面是有序超构表面的极具潜力的替代方案,往往能实现独特功能或提升性能,在需大规模应用的场景(如可持续可再生能源系统、奢侈品与建筑设计的鲜艳美学涂层)中具备尤为诱人的发展机遇。

英文摘要:

Optical metasurfaces are conventionally viewed as organized flat arrays of photonic or plasmonic nanoresonators, also called metaatoms. These metasurfaces are typically highly ordered and fabricated with precision using expensive tools. However, the inherent imperfections in large-scale nanophotonic devices, along with recent advances in bottom-up nanofabrication techniques and design strategies, have highlighted the potential benefits of incorporating disorder to achieve specific optical functionalities. This review offers an overview of the key theoretical, numerical, and experimental aspects related to the exploration of disordered optical metasurfaces. It introduces fundamental concepts of light scattering by disordered metasurfaces and outlines theoretical and numerical methodologies for analyzing their optical behavior. Various fabrication techniques are discussed, highlighting the types of disorder they deliver and their achievable precision level. The review also explores critical applications of disordered optical metasurfaces, such as light manipulation in thin film materials and the design of structural colors and visual appearances. Finally, the article offers perspectives on the burgeoning future research in this field. Disordered optical metasurfaces offer a promising alternative to their ordered counterparts, often delivering unique functionalities or enhanced performance. They present a particularly exciting opportunity in applications demanding large-scale implementation, such as sustainable renewable energy systems, as well as aesthetically vibrant coatings for luxury goods and architectural designs.
