    • A waveguide type optical device has an optical waveguide formed on a substrate, functional optical waveguides provided to the optical waveguide, at least one of an optical input end face and an optical output end face for the optical waveguide which are provided to substrate end faces which are ends at longitudinal direction sides of the substrate, and at least one of an input optical waveguide connecting the optical input end face and the functional optical waveguides, and an output optical waveguide connecting the optical output end face and the functional optical waveguides. At least one of the input optical waveguide and the output optical waveguide is formed so as to form angles other than 0 with the functional optical waveguides at the at least one of the optical input end face and the optical output end face, and so as to make angles formed to the substrate end faces at the respective sides different from 90°.
    • 波导型光学器件具有形成在基板上的光波导,提供给光波导的功能光波导,设置在基板端面的光波导的光输入端面和光输出端面中的至少一个, 在基板的纵向方向上端部,并且连接光输入端面和功能光波导的输入光波导中的至少一个以及连接光输出端面和功能光波导的输出光波导。 输入光波导和输出光波导中的至少一个形成为在光输入端面和光输出端面中的至少一个上形成功能光波导以外的θ以外的角度,并且 使得在与90°不同的相应侧面上的基板端面形成角度。
