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 1 (11) which has an electro-optical effect and has a thickness of 10 μm or less, an optical waveguide 2 formed 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 electrode 4 and a ground electrode 5, and the second electrode has at least a ground electrode 54 (55, 56) and is configured to apply an electric field to the optical waveguide in cooperation with the signal electrode of the first electrode.
