Title
(EN) MULTIPLE CORE MICROSTRUCTURED OPTICAL FIBRE
(FR) FIBRE OPTIQUE MICROSTRUCTUREE MULTICOEUR
Abstract
(EN)
A multicore optical fibre includes a microstructured cladding material formed from a plurality of cladding elements (101) arranged in an array and each cladding element comprising at least two different materials each having different refractive indices, and a plurality of core elements (11) formed within interstitial regions (10) between adjacent cladding elements (101). A fibre so formed may have a large number of cores per unit cross-sectional area as compared with prior art fibres, and thus allows the fibre to have relatively short distances between adjacent cores for a given required inter-core isolation. A fibre so formed has utility in many areas requiring high core density, such as inter-chip optical communication, or optical communication between circuit boards.
(FR)
L’invention concerne une fibre optique multicœur comportant une matière de gaine microstructurée formée d’une pluralité d’éléments de gaine (101) disposés dans une matrice, chaque élément de gaine étant constitué d’au moins deux matériaux différents possédant chacun des indices de réfraction différents, et d’une pluralité d’éléments de cœur (11) formés à l’intérieur de régions intersticielles (10) entre des éléments de gaine (101) adjacents. Une fibre ainsi formée peut comporter un grand nombre de cœurs par unité d’aire en coupe transversale par comparaison avec les fibres de la technique antérieure, ce qui permet d’obtenir des distances relativement courtes entre des cœurs adjacents pour une isolation entre cœurs donnée. Une fibre ainsi formée trouve une application dans de nombreux domaines nécessitant une forte densité de cœurs, notamment dans les communications optiques entre puces ou les communications optiques entre cartes imprimées.
