Title (EN) OPTICAL COUPLING SCHEME
(FR) MÉCANISME DE COUPLAGE OPTIQUE
Abstract:
(EN) The present invention provides a waveguide structure 100 for optical coupling. The waveguide structure 100 includes a first waveguide 101 embedded in a cladding 102 of a lower refractive index than the first waveguide 101, a second waveguide 103 of a higher refractive index than the cladding 102, and an intermediate waveguide 104. The first 5 waveguide 101 and the second waveguide 103 are physically arranged at the same side 104u of the intermediate waveguide 104 to establish an optical coupling between the first waveguide 101 and the second waveguide 103 through the intermediate waveguide 104. The first waveguide material has a refractive index value smaller than or equal to 3.
(FR) La présente invention concerne une structure de guide d'ondes (100) pour un couplage optique. La structure de guide d'ondes (100) comprend un premier guide d'ondes (101) incorporé dans un gainage (102) d'un indice de réfraction inférieur au premier guide d'onde (101), un second guide d'ondes (103) d'un indice de réfraction supérieur au revêtement (102), et un guide d'ondes intermédiaire (104). Le premier guide d'ondes (101) et le second guide d'ondes (103) sont physiquement agencés du même côté (104u) du guide d'ondes intermédiaire (104) pour établir un couplage optique entre le premier guide d'onde (101) et le second guide d'ondes (103) par l'intermédiaire du guide d'ondes intermédiaire (104). Le premier matériau de guide d'onde a une valeur d'indice de réfraction inférieure ou égal à (3).
