Supramolecular Organic Thin Films for Nonlinear Optics

Aim: To explore new routes for fabricating non-centrosymmetric molecular assemblies in the form of thin films for nonlinear optic Approach: One technique which was invented in our laboratory is Oblique Incidence Organic Molecular Beam Deposition (OIOMBD). The self-assembly process is based on deposition by a molecular beam at oblique incidence on an amorphous substrate and on selective hydrogen bonding between molecule endgroups. Impact: Applications include electro-optic modulation and frequency conversion in nonlinear optical waveguides.
