Glassy polymers, doped with nonlinear optical moieties, may be coated onto a variety of substrates and other polymers as guiding layers for optical waveguides. A nonzero electro-optic effect is achieved in these materials by inducing a partial alignment of the moieties. This paper describes a number of key properties of the materials and exhibits some of the features of these materials that may lead to practical integrated optical components and modules.
