Abstract: An optical device includes a thin film Lithium Niobate (LN) layer, a first optical waveguide, and a second optical waveguide. The thin film LN layer is an X-cut or a Y-cut LN layer. The first optical waveguide is an optical waveguide that is formed on the thin film LN layer along a direction that is substantially perpendicular to a Z direction of a crystal axis of the thin film LN layer. The second optical waveguide is an optical waveguide that is routed and connected to the first optical waveguide. At least a part of a core of the first optical waveguide is made thicker than a core of the second optical waveguide.

Abstract: An optical module includes a substrate on which an optical waveguide is provided; a housing that houses the substrate and includes a through path arranged on a side wall of the housing so as to extend in a direction that crosses the optical waveguide; a ferrule that houses an end portion of an optical fiber; and an optical path conversion element that is fixed on the ferrule, that is fixed on an end surface of the substrate on the end portion side of the optical waveguide, and that has a size smaller than a width of the substrate and a width of the ferrule along a longitudinal direction of the substrate. The end portion of the optical waveguide is arranged at a position close to the through path of the housing relative to a central portion in a width direction of the substrate.
