Photoinduced Motions in Azobenzene‐Based Amorphous Polymers: Possible Photonic Devices

Abstract

Couplers, filters, and polarization separators are some of the applications of azobenzene-based amorphous polymers such as the one shown in the Figure. The photoinduced orientation and randomization processes in films of these materials are discussed as is their possible exploitation in reversible optical storage, waveguides, and gratings, and as photorefractive materials.
