An optical signal modulation pathway, an electro-optic modulator and an optical transmitter. All electrodes on the optical signal modulation pathway except a reference electrode differ from the reference electrode in the material parameters of electro-optic crystals and/or the width of an electric field when the electric field acts in the transverse direction. The phases of input light signals varied by the other electrodes are greater than the phase of the input light signal varied by the reference electrode. In the case that a particular space is occupied by the entire optical signal modulation pathway, when a high level is accessed to the electrodes on the optical signal modulation pathway, as compared to the situation where only the reference electrode is present on the optical signal modulation pathway, the accumulated value of the phases of the input light signals that can be varied by the entire optical signal modulation pathway can be increased by increasing the phases of the input light signals varied, with no need of the increase in the number of electrodes or the length of individual electrodes. |
