【摘要】：与电磁波的波长相当的微结构可以对电磁波进行调制。这些调制产生了许多新的电磁现象:如金属表面等离子激元(SPP)、光子晶体、光学禁带效应等。本论文主要基于研究微腔结构对可见光的调制作用。通过分析和模拟光谱透射、反射的情况,进行光谱调控器件设计;通过磁控溅射,电子束蒸发等薄膜生长技术进行窄带滤波片和超薄纳米银吸收层研究。我们所制备的光子器件在日常生活、建筑装饰和光谱探测等众多领域有着比较广泛的应用前景。本文的研究内容主要包括:(1)通过FDTD方法分析和计算基于光子晶体、微腔谐振器件的微纳结构光学设计。(2)通过组合刻蚀(镀膜)的手段调控一维光子晶体中微腔的厚度,通过微腔谐振效应,改变器件对光的调控作用。我们的研究提供了一种简单、有效的方法来获得多通道窄带集成滤光片。(3)通过在银镜/SiO_2微腔结构上镀制超薄纳米银膜,实现吸收光谱的增强。通过改变银镜上二氧化硅厚度或者上层纳米银的厚度,超薄纳米银膜将显示不同的颜色。通过组合镀膜的方法,制作出集成彩色玻璃。
[Abstract]:Electromagnetic waves can be modulated by microstructures equivalent to the wavelength of electromagnetic waves. These modulation results in many new electromagnetic phenomena, such as metal surface plasma exciton (SPP), photonic crystal, optical band gap effect and so on. This thesis is mainly based on the study of the modulation effect of the microcavity structure on the visible light. By analyzing and simulating the transmission and reflection of the spectrum, the spectral control device is designed, and the narrow band filter and ultrathin silver absorption layer are studied by magnetron sputtering, electron beam evaporation and other thin film growth techniques. Our photonic devices have been widely used in many fields, such as daily life, architectural decoration and spectral detection. The main contents of this paper are as follows: (1) the optical design of micro-nano structure based on photonic crystal and cavity resonator is analyzed and calculated by FDTD method. (2) the thickness of microcavity in one-dimensional photonic crystal is controlled by combined etching (coating). The modulation effect of the device on the light is changed by the resonator effect of the microcavity. Our study provides a simple and effective method to obtain multi-channel narrow-band integrated filters. (3) the absorption spectra are enhanced by plating ultrathin nano-silver films on the silver mirror / SiO2 microcavity structure. By changing the thickness of silica on the silver mirror or the thickness of the silver nanoparticles in the upper layer, the ultrathin nano-silver film will show different colors. The integrated colored glass was made by the method of combined coating.
