摘要

A method of manufacturing a ridge optical waveguide (40) with low coupling losses between the ridge optical waveguide (40) and an optical fiber (5), comprising the steps following: - formation (100) of an optical waveguide on the surface of a dielectric substrate (10), the optical waveguide having a first end (A) and a second end (B) opposite the first end (A); - cutting (200) two recesses (R1, R2) parallel and spaced a distance wr on the surface of the dielectric substrate to form a ridge optical waveguide (40) of a width (wr) raised between the two recesses (R1, R2), characterized in that the cutting is such that the depth of each recess (R1, R2) evolves continuously and progressively between a zero depth at the height of the first end of the waveguide optical and a maximum depth (Hm) at a predetermined distance (lp) from this first end.
