Abstract:
The invention relates to an optical coupling device for coupling a first waveguide, for example a multi-mode waveguide, to a second waveguide, for example a single-mode waveguide. The device is formed in a core layer and comprises a focusing structure (SF) capable of converting a light beam from a target mode of the first waveguide to a target mode of the second waveguide. The focusing structure comprises a plurality of trenches (T 1 -T 4 ) made in the core layer to create a pseudo graded refractive index, itself able to convert the light beam from the target mode of the first waveguide to the target mode of the second waveguide. The scope of the invention extends to a photonic circuit comprising a single-mode waveguide, a multi-mode waveguide and a device according to the invention for coupling the single-mode waveguide to the multi-mode waveguide. The multi-mode waveguide can comprise a surface coupling network in order to allow for coupling with an optical fibre.

Claim (Index 4):
The device according to  claim 2 , wherein the width of each trench is unvarying along the direction of propagation.
