In this paper, an ultrafast optical switching for thin polymer films (polyarylans with allylic groups) is presented. It was realized using the Nd:YAG Sagnac interferometer. Investigated polymers appeared to be suitable candidates for elements of integrated optical telecommunication systems.

The investigation of the optical properties of the novel polyarylates with heterocyclic side chain groups is reported. Optical properties of the polymers obtained have been measured. Mechanical and thermal properties are also presented. The refractive index n( lambda ) and susceptibility chi /sup (1)/ have been determined for different compositions of polymers.
