摘要：
An optical waveguide substrate has a substrate (14) made of ferroelectric optical single crystal and a ridge portion (24A) projecting from a main plane of the substrate. The ridge portion has a base portion (15) made of ferroelectric optical single crystal and an optical waveguide (16) formed on the base portion. The optical waveguide substrate is made by forming at least one optical waveguide layer on a main plane of a substrate made of ferroelectric optical single crystal, and mechanically working main planes of the optical waveguide layer and the substrate to form a ridge portion projected from the main plane of the substrate. The optical waveguide substrate can reduce light transmission loss, increase extinction ratio, and improve electric field applying efficiency.
