A multiple-core optical waveguide comprises: a substrate; lower and upper waveguide core layers; a waveguide core between the upper and lower waveguide core layers; upper and lower cladding; and middle cladding between the upper and lower waveguide core layers substantially surrounding the waveguide core. Each of the lower, middle, and upper claddings has a refractive index less than refractive indices of the lower waveguide core layer, the upper waveguide core layer, and the waveguide core. Along at least a given portion of the optical waveguide, the upper and lower waveguide core layers extend bilaterally substantially beyond the lateral extent of a propagating optical mode supported by the optical waveguide, the lateral extent of the supported optical mode being determined at least in part by the width of the waveguide core along the given portion of the optical waveguide.
La présente invention concerne un guide d~ondes optiques à coeurs multiples comportant : un substrat, une couche de coeur de guide d~ondes inférieure et une couche supérieure, un coeur de guide d~ondes entre les couches inférieure et supérieure, une gaine supérieure et une gaine inférieure ainsi qu~une gaine centrale entre la couche de coeur de guide d~ondes supérieure et celle inférieure qui entoure sensiblement le coeur de guide d~ondes. Chacune des gaines (inférieure, centrale et supérieure) possède un indice de réfraction inférieur à ceux de la couche de coeur de guide d~ondes inférieure, de la couche supérieure et du coeur de guide d~ondes. Sur au moins une certaine portion du guide d~ondes optiques, les couches de coeur de guide d~ondes inférieure et supérieure dépassent sensiblement de chaque côté l~étendue latérale d~un mode de propagation optique fourni par le guide d~ondes optiques, ladite étendue étant déterminée au moins en partie par la largeur du coeur de guide d~ondes sur cette portion du guide d~ondes optiques.
