Abstract
An optical waveguide device having multiple functions or high performance, to improve the productivity of products, and to provide an optical waveguide device capable of suppressing deterioration of an operating characteristic of the optical waveguide device, including a thin plate 1 having a thickness of 20 μm or less and at least an optical waveguide 2 formed in the thin plate. The thin plate is bonded and fixed to a supporting substrate 5 with an adhesive 4 interposed therebetween, and a film having a higher refractive index than the thin plate and the adhesive is provided on a surface of the thin plate bonded and fixed to the supporting substrate so as to be in contact with at least a part of the optical waveguide. Preferably, the thin plate is formed of a material having a nonlinear optical effect or an electro-optical effect.
