Title (EN) MULTICORE OPTICAL FIBER AND METHOD FOR PRODUCING MULTICORE OPTICAL FIBER
(FR) FIBRE OPTIQUE MULTICŒUR ET PROCÉDÉ DE PRODUCTION DE CELLE-CI

Abstract:
(EN) A multicore optical fiber which is provided with: a core that is configured from quartz glass doped with at least fluorine and has a relative refractive index difference of from -0.30% to -0.10% based on the refractive index of quartz glass; and a cladding that is configured from quartz glass doped with at least fluorine and comprises a first cladding covering the outer circumference of the core and a second cladding provided on the outside of the first cladding. The relative refractive index difference between the first cladding and the core is 0.8% or more. The refractive index of the second cladding is higher than the refractive index of the first cladding, but lower than the refractive index of the core.
(FR) L'invention concerne une fibre optique multicoeur qui comporte : un cœur, qui est constitué de verre de quartz dopé avec au moins un atome de fluor et présente une différence d'indice de réfraction relatif comprise entre -0,30 % et -0,10 % sur la base de l'indice de réfraction du verre de quartz; et une gaine, qui est constituée de verre de quartz dopé avec au moins un atome de fluor et comprend une première gaine recouvrant la circonférence extérieure du cœur et une seconde gaine, prévue sur l'extérieur de la première gaine. La différence d'indice de réfraction relatif entre la première gaine et le cœur est supérieure ou égale à 0,8 %. L'indice de réfraction de la seconde gaine est supérieur à celui de la première gaine, mais inférieur à l'indice de réfraction du cœur.
(JA) マルチコア光ファイバであって、少なくともフッ素がドープされた石英ガラスから構成されるとともに、石英の屈折率を基準とした比屈折率差が-0.30%~-0.10%であるコアと、少なくともフッ素がドープされた石英ガラスから構成されるとともに、前記コアの外周を囲む第1クラッドおよび前記第1クラッドの外部に設けられた第2クラッドを含むクラッドと、を備え、前記第1クラッドと前記コアとの比屈折率差が0.8%以上であり、前記第2クラッドの屈折率は、前記第1クラッドの屈折率より高く、前記コアの屈折率より低い。
