An electro-optic modulator wherein a light waveguide is in the form of a film disposed on a prismatic substrate and beneath modulating electrodes. The substrate has opposite end faces disposed at predetermined angles to its longitudinal axis and cooperates with grating couplers on the waveguide to direct an entrance beam through the waveguide and to provide an exit beam along a predetermined path relative, e.g., parallel, to the entrance beam.
