ABSTRACT:
An electro-optic device incorporating a waveguide includes a locating electrode formed on a plate for locating an electrical phenomenon in a waveguide carried by the plate. The electrode comprises two juxtaposed flat surfaces, namely a locating surface relatively close to the waveguide and which has a relatively high electrical resistivity and a connection surface relatively far from the waveguide and which has a relatively low electrical resistivity. This juxtaposition makes it possible to eliminate at least partially deformation and/or attenuation of the guided waves. Applications of the invention include the implementation of a polarization modulator.
