Abstract
It is an object to provide an optical control device capable of realizing speed matching between a microwave and a light wave or impedance matching of microwaves and of reducing a driving voltage. An optical control device including a thin plate() which has an electro-optical effect and has a thickness of 10 μm or less, an optical waveguideformed in the thin plate, and control electrodes for controlling light passing through the optical waveguide is characterized in that the control electrodes are configured to include a first electrode and a second electrode disposed to interpose the thin plate therebetween, the first electrode has a coplanar type electrode including at least a signal electrodeand a ground electrode, and the second electrode has at least a ground electrode() and is configured to apply an electric field to the optical waveguide in cooperation with the signal electrode of the first electrode.
