Abstract
In one embodiment this invention provides a thin film waveguide electrooptic light modulator which consists of (1) a laminated assembly of a waveguiding thin film of an organic polymer which exhibits second order nonlinear optical response, and upper and lower organic polymer blend cladding layers, each of which has a lower index of refraction between about 0.002-0.02 lower than the waveguiding thin film and which exhibits second order nonlinear optical response; and (2) electrodes which are positioned to apply an electric field to the laminated assembly.
