Abstract
An optical modulation device includes a substrate. An optical waveguide is formed on the substrate. The optical waveguide exhibits an electro-optical effect. Parallel lines electromagnetically coupled with each other are formed on the substrate. The parallel lines extend at opposite sides of the optical waveguide respectively. The parallel lines are of a microstrip line structure. The parallel lines may alternatively be of a strip line structure or a coplanar line structure.
