Abstract:
(EN) [Problem] To provide an optical device capable of suppressing cutting of optical signals due to band-narrowing of an optical filter. [Solution] The optical device of the present invention is provided with a plurality of optical filters for filtering optical signals of a prescribed band from among a plurality of optical signals of different wavelengths. The plurality of optical filters is configured such that a portion of each of the optical filter pass bands (13_1, 13_2, 13_3), which pass each of optical signals of mutually adjacent wavelengths (15_1, 15_2, 15_3), are superimposed on each other.
(FR) Le problème décrit par la présente invention est de fournir un dispositif optique apte à supprimer la découpe de signaux optiques causée par un rétrécissement de bande d'un filtre optique. La solution selon la présente invention concerne un dispositif optique qui comprend une pluralité de filtres optiques pour filtrer des signaux optiques d'une bande prescrite parmi une pluralité de signaux optiques de différentes longueurs d'onde. La pluralité de filtres optiques est configurée de telle sorte qu'une partie de chacune des bandes passantes de filtre optique (13_1, 13_2, 13_3), qui laissent passer chacun des signaux optiques de longueurs d'onde mutuellement adjacentes (15_1, 15_2, 15_3), sont superposées les unes sur les autres.
(JA) [課題]光フィルタの帯域狭窄によって光信号が削られることを抑制することが可能な光デバイスを提供することである。 [解決手段]本発明にかかる光デバイスは、波長が異なる複数の光信号の中から所定の帯域の光信号をフィルタリングする光フィルタを複数備えている。前記複数の光フィルタは、互いに隣接する波長の光信号(15_1,15_2,15_3)を各々通過させる各々の光フィルタの通過帯域(13_1,13_2,13_3)の一部が互いに重畳するように構成されている。
