Abstract
An electro-optic device is provided with a substrate, an optical waveguide formed of a lithium niobate film with a ridge shape on the substrate, and an electrode that applies an electric field to the optical waveguide. The optical waveguide includes a first waveguide section provided at least in an electric field application region applied with the electric field and having a thickness of 1 μm or larger and a second waveguide section provided in a region other than the electric field application region and having a thickness of 0.3 μm or larger and less than 1 μm.
