Abstract

We report on a novel class of optically nonlinear polymeric materials realized by processing onto a substrate a combination of molecules and polymers comprising hyperpolarizable and thus optically nonlinear molecular groups, liquid crystal moieties, and chiral moieties. Since processing of this combination of materials leads to a spontaneously noncentrosymmetric bulk orientation of the hyperpolarizable moieties in its thermodynamically most stable state, the material exhibits second-order nonlinear-optical properties that can be used for second-order nonlinear-optical effects such as frequency doubling of optical radiation, the linear electro- optic of Pockels effects, magneto-optic effect, nonlinear dichroism, etc. We will present and discuss the experimental results concerning the nonlinear-optical properties obtained via frequency doubling of light in these materials.
