Research Abstract	1.高速非線形パルス伝送のための分散マネージメント伝送路の設計と製作・160Gb/s伝送における伝送路ファイバの分散ばらつきの影響を数値シミュレーションを用いて明らかにした。準線形伝送方式では、受信端において適応的な分散補償をすることによって分散ばらつきからくる特性劣化を回避することができるが、分散マネージメントソリトン伝送では、局所的な分散の変動が伝送路の非線形性を介して非可逆な波形劣化をもたらすため、受信端における分散補償が有効でないことを示した。・偏光子を用いた偏波モード分散補償に関して、補償器を伝送路中のどの位置に置けば最適な効果が得られるかについて考察した。また、10Gbit/sのRZ光送受信機と平均群遅延時間差が47psのPMDエミュレータを用いて実験を行い、偏光子を伝送路に分布的に配置した場合、配置数を4とすると、自由度が2(偏光制御+固定偏光子)の従来型PMD補償器より優れた補償効果が得られ、平均パワーペナルティ0.4dBを得られることがわかった。・双峰ソリトンが存在可能なパラメータ領域を数値シミュレーションによって詳細に調べるとともに、双峰ソリトンに対する分散スロープおよび増幅器雑音の影響について調べた,その結果、適当な分散スロープ補償を行なえば、双峰ソリトンが伝送可能であることおよび増幅器雑音によるタイミングジッタの大きさは単峰ソリトンとほとんど変わらないことを示した。また、一般に分散マネージメントソリトンはエネルギーを漏洩しながら伝搬するパルスであることを数値シミュレーションにより示した 2.ファイバ中の非線形光学効果を利用した信号処理の理論と実験・高非線形ファイバ中のソリトン効果およびスペクトル拡散効果を利用した信号再生器の解析を行い、高速伝送におけるそれらの有効性と特徴を明らかにした。また、スペクトル拡散効果を利用した信号再生器は、伝送路の偏波モード分散補償や偏波モード分散モニタにも使えることを明らかにした。・ファイバ中におけるスーパーコンティニューム光の発生現象を利用した全光アナログ-ディジタル変換法を提案し、原理確認実験を行なった。また、ファイバの自己位相変調効果に基づく波長変換操作を実験的に示し、これが光バーストスイッチ等に応用できることを示した。
