Claim 0:
1. An optical circuit in which optical waveguides to be connected to optical fibers are formed, comprising:
a first alignment optical waveguide longitudinally extending between a first end and an opposing second end and having a core with an optical axis direction, the second end of the first alignment optical waveguide being disposed at an optical waveguide edge face;
a first light path changing member disposed at the first end of the first alignment optical waveguide, the first light path changing member being configured to change a path of light extending along the optical axis direction of the core of the first alignment optical waveguide to a direction perpendicular to the optical axis direction of the core of the first alignment optical waveguide;
a second alignment optical waveguide longitudinally extending between a first end and an opposing second end and having a core with an optical axis direction, the second end of the second alignment optical waveguide being disposed at the optical waveguide edge face;
a second light path changing member disposed at the first end of the second alignment optical waveguide, the second light path changing member being configured to change a path of light extending along the optical axis direction of the core of the second alignment optical waveguide to a direction perpendicular to the optical axis direction of the core of the second alignment optical waveguide, the second light path changing member being separate and spaced apart from the first light path changing member; and
a waveguide array disposed between the first light path changing member and the second light path changing member and extending to the optical waveguide edge face.
