Some embodiments are directed to a method for manufacturing photonic waveguides and to photonic waveguides manufactured by this method.

Method for manufacturing a photonic waveguide and photonic waveguide manufactured by said method

A method for producing a ridge optical waveguide having low coupling losses between the ridge optical waveguide and an optical fiber includes forming on the surface of a dielectric substrate an optical waveguide having a first end and a second end opposite the first end; cutting out two parallel recesses spaced apart by a distance wr on the surface of the dielectric substrate to form a rigid optical waveguide with an increased width (wr) between the two recesses. The recesses are cut such that the depth of each recess changes continuously and gradually between a zero depth at the height of the first end of the optical waveguide and a maximum depth (H) at a pre-determined distance (I) from the first end.
