1. light control element comprises that having electrooptical effect and thickness is a plurality of photocontrol portion that thin plate, the optical waveguide that on this thin plate, forms below the 10 μ

  • m and being used for is controlled at light that this optical waveguide propagates, it is characterized in that,On at least a portion of this photocontrol portion, the control electrode that is used for this optical waveguide is applied electric field is made up of the 1st electrode and the 2nd electrode that clip this thin plate configuration,The 1st electrode has signal electrode and ground-electrode, and the 2nd electrode has ground-electrode at least, and the signal electrode cooperation that constitutes with the 1st electrode applies electric field to this optical waveguide,Be connected with the ground-electrode of configuration overleaf or the control signal distribution of any one formation in the microstrip line through the coplanar type circuit that only on the coplanar type circuit that disposes on the surface of thin plate, surface at thin plate, disposes between a plurality of photocontrol portion, be set to roughly the same the time of arrival of light and electric signal.
