We describe the realization of an ultra fast deflector in Ti-diffused LiNbO3 waveguide. We realize practically in 100 ns a linear scanning of an optical beam crossing the component. A driving voltage of 35 volts gives a deflection angle of one degree and the voltage causing deflection to the first spot position (following the Rayleigh resolution criterion) is 10 volts.
