Summary form only given. The last years have witnessed an intense investigation of light propagation in periodic structures. These structures are usually referred to as photonic band gap (PBG) crystals. In this presentation we describe the method of fabrication of PBG materials that may have periodic modulation of refraction index, absorption coefficient and the nonlinearity as well. The method is based on the layer-by-layer self-assembly technique. We present results of a study of polymeric films and the multilayer structures with a very high content of multivalent metal cations formed by taking advantage of stepwise coordination of polyanion and multivalent metal cations.
