Abstract
L'invention concerne un guide d'ondes multi-modes et un procédé pour la formation d un guide d'ondes optiques propre à propager de la lumière selon des modes multiples avec couplage de puissance entre des modes sélectionnés. Ce guide d'ondes comprend une âme en verre, une gaine en verre entourant ladite âme, ladite âme présentant un indice de réfraction supérieur à l'indice de réfraction de ladite gaine, et des perturbations cylindriques ménagées dans ladite âme, lesdites perturbations étant espacées dans le sens longitudinal de ladite âme et comportant des variations d'indice de réfraction en anneaux au sein de ladite âme. Système de télécommunication.
