ABSTRACT:
Organic groups covalently bound to a polymer backbone provide second or third order nonlinear susceptibilities to the polymer. In another aspect, a method is disclosed for providing the novel polymers of the invention. Polymers of the invention can be directionally oriented to provide useful optically nonlinear media for use in nonlinear optical devices such as optical switches or light modulation devices.
