Structures of connecting optical waveguide parts and holding parts of holding optical input members, and a method of producing the same

摘要

A connecting structure includes an optical waveguide part, a holding part of holding an optical input member, and an adhering part adhering the optical waveguide part and holding part. The optical waveguide part includes an optical waveguide substrate including an optical waveguide. At least one of the holding part and optical waveguide part includes a recess and an adhesive face adjacent to the recess. The adhering part is provided on the adhesive face and in a single region distant from the optical waveguide substrate in a direction of thickness of the optical waveguide substrate. The recess is provided between the adhering part and optical waveguide substrate. A space is provided between an end face of the optical input member and an end face of the optical waveguide.
