Abstract:
One manner of construction of robust, thin film materials with large second-order optical nonlinearities is the covalent self-assembly of aligned arrays of high-β molecular chromophores into multilayer superlattices. the dispersion of the large second harmonic generation (SHG) response in a self- assembled (SA) film containing stilbazolium chromophore building blocks is disclosed, as well as the fabrication of SHG waveguides with such materials.
