Paper Abstract

Azobenzene containing amorphous polymers are used to fabricate thin films that can act as optical waveguides. Furthermore, stable surface relief structures such as gratings can be holographically inscribed onto the films using low and medium power lasers. The grating depth and spacing can easily be controlled with the depth varying from 15 nm to several hundred nanometers and spacing varying from 170 nm to 3 micrometers. These thin-film structures can then be designed to act as optical devices such as optical couplers, optical filters and birefringence films. We will describe the method of the fabrication ofthe surface relief structures and suinmarise the theories proposed for the mass polymer movement that produce these structures.
