ABSTRACT:
An optical modulation device includes a substrate, and a dielectric member having first and second surfaces opposite to each other. An optical waveguide extends on the first surface of the dielectric member and exhibits an electro-optical effect. First and second parallel lines are electromagnetically coupled with each other, and are of a microstrip line structure. The first line has a first line member and a ground plane, and the second line has a second line member and the ground plane. The first line member and the second line member extend on the first surface of the dielectric member and extend at opposite sides of the optical waveguide respectively. The ground plane extends between the substrate and the second surface of the dielectric member.
