Title (EN) MILLIMETER SCALE LONG GRATING COUPLER
(FR) COUPLEUR À RÉSEAU LONG D'ÉCHELLE MILLIMÉTRIQUE
Abstract:
(EN) A millimeter scale weak grating coupler comprising a silicon waveguide having bars of overlay material of length (a) disposed periodically at a period (Λ) adjacent the silicon waveguide whereby a uniform grating output is achieved.
(FR) L'invention concerne un coupleur à réseau faible d'échelle millimétrique comportant un guide d'ondes en silicium ayant des barres de matériau de recouvrement de longueur (a) disposées périodiquement à une période (Λ) adjacente au guide d'ondes en silicium, permettant d'obtenir une sortie de réseau uniforme.
