integrated optical structure comprising a substrate, at least a portion of waveguide not buried as well as its of

摘要

The invention concerns an optics-integrated structure comprising in a substrate an optical guide having at least a non-buried guide portion and on the substrate surface at least an overlapping element (5) located above the non-buried guide portion and designed to isolate said guide portion, a light wave propagating therein. The invention is applicable to optics-integrated components such as in particular optical amplifiers, optical multiplexers, optical divider, optical couplers and the like.
