Abstract

Methods are described for fabricating waveguides having an "embedded" (or "submerged") ridge or heterostructure in liquid-phase epitaxy. The concept is based on grooves (11), which are formed in the substrate (10) and which are preferentially filled when layers are grown on this substrate in liquid-phase epitaxy. The interruption of the epitaxial growth necessary in conventional methods, and the etching at this interruption stage are dispensed with. <IMAGE>
