Abstract
A multilayer nonlinear dielectric optical structure is formed by coextruding at least two polymeric materials, components (a) and (b), using a multiplying element; the structure contains a plurality of alternating layers (A) and (B) represented by formula (AB) , where x=2 , and n is the number of multiplying elements; at least one of the components (a) and (b) exhibits nonlinear optical response. These structures perform a variety of nonlinear optical functions including all-optical switching and passive optical limiting.
