Abstract
A process is provided for fabricating an integrated optical circuit comprising waveguides having different structures. In this process the coupled ends of the different structures are designed to enlarge the lateral mode size of optical waves issuing from them. The optical coupling losses of the integrated optical circuit obtained in this way are considerably reduced.
