Abstract
We present the fabrication of high quality non-uniform Bragg gratings in planar poly(4-BCMU) channel waveguides using an optimized photobleaching set-up and report the optical characterization of the resulting photonic band gap. The suitability of our system to all-optical switching phenomena in different geometries as a result of non-linear wave propagation effects will be shown and discussed. Our results contribute to open up the wide field of device applications in integrated optics based on periodically structured planar polymer waveguides.
