Abstract[English]
An optical mode coupler is provided. The optical mode coupler comprises a waveguide structure, the waveguide structure comprising: a waveguide, the waveguide having a proximal end, the proximal end situated at a distance from an edge facet of the waveguide structure; a cladding material encasing the proximal end of the waveguide; and a mode-matching region formed of the cladding material and situated between the proximal end of the waveguide and the edge facet of the waveguide structure, the mode-matching region configured to match a mode of light supported by the waveguide to a fibre mode supported by an optical fibre at the edge facet of the waveguide structure.[French]
L'invention concerne un coupleur de mode optique. Le coupleur de mode optique comprend une structure de guide d'ondes, la structure de guide d'ondes comprenant : un guide d'ondes, le guide d'ondes ayant une extrémité proximale, l'extrémité proximale étant située à une certaine distance d'une facette de bord de la structure de guide d'ondes ; un matériau de gainage enveloppant l'extrémité proximale du guide d'ondes ; et une région d'adaptation de mode formée du matériau de gainage et située entre l'extrémité proximale du guide d'ondes et la facette de bord de la structure de guide d'ondes, la région d'adaptation de mode étant configurée pour correspondre à un mode de lumière supporté par le guide d'ondes à un mode fibre supporté par une fibre optique au niveau de la facette de bord de la structure de guide d'ondes.
