An attractive and challenging approach to the construction of robust, thin film materials with large second-order optical nonlinearities is the covalent self-assembly of aligned arrays of high-(beta) molecular chromophores into multilayer superlattices. In this paper, we describe the dispersion of the large second harmonic generation (SHG) response in a self-assembled film containing stilbazolium chromophore building blocks. We also describe a new approach to fabricating SHG waveguides with such materials as well as preliminary confirmatory experimental results.
