ABSTRACT:
In an optical module such as an optical branching and multiplexing device used in an optical communication system, optical waveguides are formed on a surface of an optical waveguide substrate and optical fibers are held by arranging guide grooves on an optical fiber arranging substrate. The optical waveguide substrate has positioning guide grooves which can engage with the arranging guide grooves. The pitch of the optical waveguides on end faces of the optical waveguide substrate coincide with the pitch of the arranging guide grooves, so that the optical fibers and the optical waveguides are coupled accurately without any adjustment.
