| 英文摘要 | An optical control device such as an optical switch includes two waveguides formed in an electrooptical substrate. Two control electrodes are preferably formed respectively above the two waveguides through a buffer layer. The optical control device is further provided with additional electrodes formed where there is no waveguide therebelow. The additional electrodes are connected with either of the two control electrodes, so that there generates an electric field not only in the direction vertical to the surface of the substrate but in the direction parallel to the surface thereof. |
