Title (EN) OPTICAL FIBER AND METHOD FOR MANUFACTURING OPTICAL FIBER
(FR) FIBRE OPTIQUE ET PROCÉDÉ DE FABRICATION DE FIBRE OPTIQUE
(JA) 光ファイバおよび光ファイバの製造方法
Abstract: front page image
(EN) An optical fiber provided with a multimode fiber that has the following: a core, the maximum refractive index of which is higher than the refractive index of pure SiO2; a layer that is formed in the center of the core, is continuous in the lengthwise direction of the optical fiber, and does not contain germanium; and a layer, surrounding the layer that does not contain germanium, that is doped with germanium and has a power-law index profile.
(FR) L'invention concerne une fibre optique pourvue d'une fibre multimode qui possède les éléments suivants : un cœur, dont l'indice de réfraction maximal est supérieur à l'indice de réfraction du SiO2 pur ; une couche qui est formée dans le centre du cœur, est continue dans le sens de la longueur de la fibre optique, et ne contient pas le germanium ; et une couche, entourant la couche qui ne contient pas de germanium, qui est dopée avec du germanium et possède un profil à gradient exponentiel.
(JA)  光ファイバであって、最大屈折率が純粋SiOの屈折率より高いコアと、コアの中心に形成され、光ファイバの長手方向にわたり連続して、Geを含まない層と、Geを含まない層の外周に、屈折率分布がα乗分布である、Geがドープされた層と、を有するマルチモードファイバを備える。
