Design and Photonics of Liquid-Crystalline Polymer Materials

摘要

Azobenzene-containing polymer,in which a change in birefringence can be induced by photoisomerization,is one of promising materials for holographic applications.To develop high-performance holographic materials using azobenzene polymers,it is necessary to prepare optically transparent thick films with capability of a large photoinduced change in refractive index to obtain high diffraction efficiency and fast response in the Bragg regime.
