Waveguide type optical device
A waveguide type optical device has an optical waveguide formed on a substrate, functional optical waveguide an optical input end face and an optical output end face which are provided to respective substrate end faces an input optical waveguide connecting the optical input end face and the functional optical waveguides, an output optical waveguide connecting the optical output end face and the functional optical waveguides, and a signal light monomode optical fiber. 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 optical input end face and the optical output end face respectively, such that an angle between each of the input optical waveguide and the output optical waveguide with respect to a corresponding one of the substrate end faces is other than 90°.
