摘要: The combination of an electro-optic substrate the refractive index which is changed by electric field applied to same and a pair comb-shaped interdigital diffraction electrodes formed on surface said provides electrically controllable grating, can be used as optical modulator laser beam. An example lead-zirconate-titanate ceramic electrode composed metal.
