Abstract

　従来の分散補償器は、波長選択スイッチなどを利用するリング・メッシュ型構成のネットワークでは、ＷＤＭ波長ごとに異なる分散値を設定したいという要請に十分に応えるものではなかった。装置の小型・低消費電力化は不十分であり、波長毎に分散特性を簡単に柔軟に変更することは困難であった。本発明の分散補償器は、離散的な位相を与える空間位相制御素子を含む汎用の光学部品を用いて、集光ビーム半径と空間位相制御素子のピクセルの関係を適切に設定することにより、多様な分散補償特性を与えることができる。離散的な位相を与える空間位相制御素子上の複数のピクセルと通信チャンネル帯域との対応関係に着目し、柔軟な分散特性の変更を可能とし、ＷＤＭ波長ごとに独立した分散値の設定を実現する。
