A Pockels-effect electro-optical modulator including a light guide having a core made of an inorganic amorphous material, and on which a structure is superposed that is made up of two electrode-forming layers between which an electro-optical polymer is interposed, said modulator being characterized in that said structure is superposed directly on the material of the core of the light guide. The transitions between the active and passive zones are advantageously adapted to minimize losses.
