Abstract
An optoelectronic device for optical coupling between different dimensioned waveguides has an arrangement forming a narrow waveguide and an arrangement forming a broad waveguide, which extend parallel to one another and are superimposed with each other to provide a superimposing wave guidance in a region and transverse dimensions of the narrow waveguide are continuously reduced to zero in the shape of a taper in a second region so that only the broad wave guidance on the basis of the broad ridge fashioned in the broad waveguide are present in a region adjoining this second region having the taper.
