The PE technology has been applied in the fabrication of a wide bandwidth interferometric modulator in X-cut Lithium Niobate. The utilization of dilute melt of Benzoic Acid and Lithium Benzoate as source in the H-Li exchange process, and the introduction of a subsequent appropriate thermal annealing allow to obtain high quality channel waveguide characterized by high long term stability, high electrooptical efficiency , low propagation losses, low fiber-waveguide insertion losses and high resistance to the laser radiation induced damage. The main advantages of this modulator in comparison with the similar Ti-induffusion based device are the lower fabrication cost and the possibility to handle higher optical power, allowing higher dynamic range of the signal processing system.
