The present invention relates to a method and a device for aligning wave guides such as optical fibers on a carrier. In order to fix the wave guide such as optical fibers on a carrier made of e.g., silicon, adhesive and a lid have been used, wherein the optical fibers have been placed in grooves on the carrier and the adhesive supplied to capillaries between the optical fibers in the grooves on the carrier and the attached lid, whereby a fixation of the optical fibers on the carrier has been obtained. In order to improve the adhesive penetration and to minimise the risk for air bubbles being formed between the carrier and the lid the lid has been formed divided comprised of for example two ribs (14,15) arranged in parallel. The ribs when fastened onto the carrier will form two short capillaries between the ribs and the carrier with the optical fibers whereby it becomes easier to introduce the adhesive between the ribs and the optical fibers on the carrier and the adhesive will be able to be ventilated better.
