ABSTRACT:
An optical waveguide device including a support substrate, a glass substrate, and a thin film layer formed on at least one of the substrates, if required. The support substrate and the glass substrate are bonded through direct bonding, and the glass substrate includes an optical waveguide as a part thereof. A layer having a refractive index lower than that of the glass substrate may be formed on the glass substrate. A method for fabricating such an optical waveguide device is also provided.
