1. An optical branched waveguide comprising:

  • a substrate;

    a first optical waveguide formed on the substrate;

    a second optical waveguide formed on the substrate so as to intersect with the first optical waveguide at a predetermined angle; and

    an optical element which is provided at an intersecting region of the first optical waveguide and the second optical waveguide, allows part of an incident light guided through the first optical waveguide to pass therethrough and guides it to the first optical waveguide, and reflects part of the incident light and guides it to the second optical waveguide.
