3b03 Fabrication of photo responsive multi-bilayered mirror using azobenzene containing polymer

Abstract

Multi-bilayered films having optical periodicity with different refractive indices have been studied for one dimensional photonic crystal (1DPC) showing photonic band gap (PBG) in which the existence of a certain energy range of photons is forbidden. In this study, photo-responsive multi-bilayered film consisting of azobenzene polymer liquid crystals and polyvinyl alcohol were prepared on a glass substrate by spin coating, and we investigated effects of azobenzene structures on their optical and photoresponsive properties.
