Abstract

New nonlinear optical materials for waveguides are needed to enhance the ability of the waveguides to perform electro-optic tasks. It has been particularly difficult to obtain bulk materials with large second order nonlinear susceptibilities. This difficulty arises from the fact that many hrghly nonlinear materials form centrosymmetric crystals yielding no second order susceptibility. In structures where the vector direction of highly nonlinear molecules have projections on the same external reference frame, the effective nonlinearity of all the molecules can result in a high bulk nonlinearity, If this material can be fabricated into a waveguide, high laser power densities can be maintained over long path lengths further enhancing the efficiency of the nonlinear interaction such as frequency doubling and parametric mixing.
