PA29 Fabrication and optical properties of high order reflection multi-bilayered film

Abstract

Multi-bilayered films consisting of two stacked materials with different refractive indices reflect specific wavelength of light. It was found that multi-bilayered films having larger thickness ratio of two stacked materials reflect not only primary reflection but also high order reflection by simulation. In this study, we fabricated high order reflection multi-bilayered films by spin-coating method, and discussed about the optical properties. Furthermore, ON/OFF switching of the reflection was investigated by introducing azobenzene liquid crystal polymer into the multi-bilayered films.
