Claim 6:
7. A method for connecting the optical fibers to the optical circuit as recited in claim 1, the method comprising:
inserting a core wire of a first alignment optical fiber and a second alignment optical fiber into a first guide hole and a second guide hole, respectively, of an optical connection part, the optical connection part having a front face and an opposing back face with the first guide hole and the second guide hole extending therebetween;
placing a first light receiving device over the first light path changing member and a second light receiving device over the second light path changing member;
movably positioning the front face of the optical connection part directly against the optical waveguide edge face of the optical circuit;
transmitting light from the first alignment optical fiber and the second alignment optical fiber to the first alignment optical waveguide and the second alignment optical waveguide, respectively;
monitoring light intensities of the light exiting the first alignment optical waveguide and the second alignment optical waveguide using the first light receiving device and the second light receiving device while moving the optical connector part relative to the optical waveguide edge face; and
securely fixing the optical connection part to the optical waveguide edge face of the optical circuit when the optical connection part is positioned so that the monitored light intensities are the highest.
