3C02 Studies on the molecular orientation of azobenzene polymer liquid crystal in one-dimensional photonic crystal

Abstract

Photonic crystals show the photonic band gap which prohibits propagation of the photon in a certain energy range. Multi-bilayered films are known as one dimensional photonic cystals having optical periodicity with different refractive indices. Multi-bilayered films reflect light of specific wavelength, and the reflection wavelength is related to the film thickness and refractive indices of each materials. In this study, we investigated the structure effect of azobenzene polymer on out-of-plane molecular orientation behavior, and reported switching of molecular orientation in one dimensional photonic crystal.
