Abstract:
An optical modulation device includes a substrate, a slot waveguide formed by arranging a pair of electrodes in a groove formed on one side of the substrate and by filling the groove with an electro-optical material, a dielectric film that covers a surface of the electro-optic material filled in the slot waveguide, and a plate member that covers the slot waveguide and is bonded to the dielectric film with an adhesive resin.
