SELF-ASSEMBLED SUPERLATTICES AND WAVEGUIDES PREPARED FOR USE THEREWITH

摘要

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- beta 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. An example of the multilayer superlattices comprises optically non-linear self-assembled multilayers (10) formed on a substrate (15) and an optically linear polymer layer (20) formed on the non-linear layer (10).
