Abstract: An optical waveguide device using a thin substrate having an electro-optical effect and having a thickness of 10 μm or less, in which, even when the thin substrate is adhered to a supporting substrate, breakage of the thin substrate or supporting substrate is suppressed, and performance deterioration such as optical loss due to fine cracks is also suppressed. The optical waveguide device includes a thin substrate, which has an electro-optical effect and a thickness of 10 μm or less, and in which an optical waveguide is formed, and a supporting substrate that is adhered to the thin substrate through an adhesion layer. A structure is formed in a thin-substrate side surface of the supporting substrate, and the supporting substrate is annealed at a high temperature that is equal to or lower than the Curie temperature after forming the concavo-convex structure and before being adhered to the thin substrate.

Abstract: An optical waveguide device that uses a thin substrate having an electro-optical effect and a thickness of 10 μm or less, in which slab propagation light that is reflected from an end face of the device is removed and thus deterioration in an operational characteristic is suppressed. The optical waveguide device includes: a thin substrate which has an electro-optical effect and thickness of 10 μm or less, and in which an optical waveguide is formed; and a supporting substrate that is adhered to the thin substrate through an adhesion layer. An antireflective film is formed on a part of a side surface of the optical waveguide device.

Abstract: To effectively prevent the acceleration of the drift phenomenon generated by the application of a high electric field to a substrate through a bias electrode in a waveguide type optical element. A waveguide type optical element includes a substrate (100) having an electro-optic effect, two optical waveguides (104 and 106) disposed on a surface of the substrate, a non-conductive layer (120) which is disposed on the substrate and is made of a material having a lower dielectric constant than the substrate, and a control electrode (150) which is disposed on the non-conductive layer and is intended to generate a refractive index difference between the two optical waveguides by respectively applying electric fields to the two optical waveguides, and the non-conductive layer is constituted of a material which includes silicon oxide, an oxide of indium, and an oxide of titanium and has a ratio between a molar concentration of the titanium oxide and a molar concentration of indium oxide of 1.2 or more, and a voltage generating an electric field of 1 V/μm or more in the substrate is applied to the control electrode.
