表面等离激元是一种在金属与介质交界面处发生的电子集群震荡,是一种由入射光引起的表面电磁波,其特点在于高度局域化。基于表面等离激元实现对微纳光电器件的精准调控成为目前科研热点。本文聚焦在人工微纳结构的光谱调控器件最新进展,综述通过设计不同的微纳结构,改变结构参数,材料属性,机械拉伸柔性衬底等方法对光谱进行精准调控,实现了结构色从静态到动态的调谐改进。可实时动态调谐的滤波器在军事、国防、信息安全等领域拥有广阔的应用前景。

Surface plasmon is an electron cluster oscillation occurring at the interface between metal and medium.It is a surface electromagnetic wave caused by incident light and is characterized by high localization.The precise regulation of micro-nano-optical devices based on surface plasmon has become a hotspot.This paper focuses on the latest developments in spectral control devices for artificial micro-nano structure.It summarizes the accurate control of the spectrum by designing different nano-structures,changing structural parameters,material properties,and mechanically stretching flexible substrates,so as to realize the tuning improvement from static to dynamic.Filters that can be dynamically tuned in real time have broad application prospects in the fields of military,national defense,information security and other fields.
