Abstract

In a method for manufacturing an integrated, optical waveguide component having fiber couplings, a substrate component and a cover component are used, the cover component being obtained by forming a positive-negative replica of the substrate component. To separate the optical waveguide pattern region from the regions of the fiber couplings, grooves, as well as corresponding webs, are provided transversely to the fiber couplings. The method eliminates the need for carrying out the fiber adjustment and the waveguide formation in one process.
