摘要

结合薄膜光学、导波光学和衍射光学制备的亚波长微纳结构器件,具备制作新型功能光学元件的潜力,是当今光学领域备受关注的研究热点.笔者介绍了亚波长导模共振结构应用于可调谐滤波器、彩色图像再现,及其周期性孔阵列结构制备的可调谐滤波器.这些研究展示了微纳米尺度的光学结构不同于宏观尺度的新特征,及其在新技术的广阔前景和科技创新中的重要作用.%Subwavelength micro-nano structure devices combined with thin film optics, guided-wave optics and diftractive optics had the potential to produce new functional optical components. It became one of the most popular fields in the current scientific research and industrial development. This paper describes the characteristics of subwavelength guided-mode resonant structure and the applications of tunable filter, colored image reproduction. Moreover, the design and fabrication processing of the terahertz filter are also presented with periodic microstructure. All of the results showed the new features of the micro and nano-scale optical structure are different from the macroscopic scale. Micro-nano optical devices played an important role in new technology and presented broad prospects of science and technology.
