ABSTRACT:
An optical waveguide chip assembly in which a plurality of optical waveguide patterns and two positioning grooves are laterally arranged is prepared by forming a plurality of optical waveguide patterns and two positioning grooves on a wafer in parallel to each other and cutting the wafer. Separately from this, an optical fiber array assembly having a plurality of optical fiber array cables and two guide pin holes is prepared. The optical waveguide chip assembly and the optical fiber array assembly are joined while aligning by the guide pins and then divided into units of individual optical waveguide modules. A large number of optical waveguide modules can be made with a good efficiency, and the mass productivity is improved. Since a plurality of optical waveguide modules are made by the same positioning, variations among products can be reduced.
