[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.
