Abstract

　光ファイバを用いた光伝送路が、中心に位置し空孔が構成するコアと、コアの外側に位置する外側クラッドと、コアと外側クラッドの間に位置し外側クラッドとは屈折率が異なる媒質を周期的に配列してブラッグ回折格子を形成した内側クラッドとを有し、ブラッグ回折格子が形成するフォトニックバンドギャップ内の所定の使用波長の光を伝搬するフォトニックバンドギャップ光ファイバと、フォトニックバンドギャップ光ファイバに隣接して接続し使用波長においてフォトニックバンドギャップ光ファイバの波長分散値よりも小さく０ｐｓ／ｎｍ／ｋｍ以上の波長分散値を有するとともにフォトニックバンドギャップ光ファイバよりも大きいＤ／Ｓ値の光ファイバとを備える。これによって、フォトニックバンドギャップ光ファイバの低光学非線形性と低伝送損失特性とを活用しながら、光伝送路の波長分散特性を容易に補償できる光通信システムを提供する。
