Abstract
This invention provides a thin film waveguide electrooptic intensity modulation device. The thin film waveguide is an isotropic organic medium which exhibits nonlinear optical response. The device is adapted to modulate waveguided radiation by refractive index change commensurate with change in an applied electric field.
