Photoinduced Birefringence, Holographic Surface Gratings and Photorefractive Properties of Azo Polymers.

Abstract

Films of amorphous high-Tg polymers show an unexpected versatility in terms of device utilization. Reversible optical storage is possible by photoinducing birefringence, and either dots or waveguides can be imprinted. Surface highly efficient gratings can be inscribed, and they can also serve as entry/exit points into waveguides. Finally, switches can be designed by using photorefractive properties. jg p.2
