Title (EN) MULTI-CORE POLARIZATION MAINTAINING FIBER
(FR) FIBRE MULTICŒURS DE MAINTIEN DE POLARISATION
(JA) マルチコア偏波保持ファイバ
Abstract:
(EN) This multi-core polarization maintaining fiber 10 is provided with: a plurality of cores 11, a clad 12 which encloses the plurality of cores 11, and a plurality of stress imparting parts 15 which are arranged so that the plurality of cores 11 are interposed therebetween in an area enclosed with the outer circumference of the clad 12, wherein the cross-sectional area of the stress imparting part 15 is larger than that of the core 11, and some of the plurality of stress imparting parts 15 are disposed along one direction and others are disposed along another direction different from the one direction.
(FR) La fibre multicœurs de maintien de polarisation 10 est pourvue : d'une pluralité de cœurs 11, d'une gaine 12 qui renferme la pluralité de cœurs 11 et d'une pluralité de parties de transmission de tension 15 qui sont agencées de telle sorte que la pluralité de cœurs 11 sont intercalés entre celles-ci dans une zone entourée par la circonférence externe de la gaine 12, la section transversale de la partie de transmission de tension 15 étant plus grande que celle du cœur 11, et certaines parties de la pluralité de parties de transmission de tension 15 étant disposées le long d'une direction et d'autres parties étant disposées le long d'une autre direction, différente de la première direction.
(JA) マルチコア偏波保持ファイバ10は、複数のコア11と、複数のコア11を囲むクラッド12と、クラッド12の外周で囲まれる領域内において複数のコア11のそれぞれを挟むように設けられた複数の応力付与部15と、を備え、応力付与部15の断面積はコア11の断面積より大きく、複数の応力付与部15は、一の方向に沿って複数配置されるとともに当該一の方向とは異なる他の方向に沿って複数配置される。
