Abstract:

Recently in our laboratory, improved optical quality films of PBZT were fabricated by extruding low concentration solutions in methane sulphonic acid. The films, even though being extruded from an apparatus that was not designed for optical films, showed a dramatic improvement in the optical quality over those which were used in the previous measurements. X3 measurements of these films also indicated that the x3 values of these films were substantially higher than the previously reported values. However, the films were not of sufficient quality for wave-guiding experiments. This study was to identify the optical defects of the films so that the technique and the equipment can be improved to generate wave-guiding quality films with other NLO polymers. Two classes of defects have been identified and will be described in this report. The equipment modifications being implemented are documented.
