Title: 大コア穴あきファイバ
IPC: G02B6/02
Filed: 2005-01-13
Abstract: 様々なタイプの穴あきファイバは、光伝搬をもたらす。様々な実施例において、例えば、大きなコアの穴あきファイバは、少数の層に配置された大きな穴で形成されたクラッド領域を有する。コアの周りの穴の層或いは列の数は、信号の基本モードと高次モードの漏れ損失を荒く調整するために使用され、それによって、与えられた長さのファイバに渡っての漏れで非基本モードが実質上除去されることを可能にする。基本モードの望ましい漏れ損失での望ましい動作をもたらすために、漏れ損失の細かい調整が穴寸法及び或いは穴間隔を調節することで行われる。結果としての穴あきファイバは、シングルモードを伝搬する従来のファイバと通常のファイバと比べるとき、大きな穴寸法と間隔とをもち、従って大きなコアをもつ。穴あきファイバの選択されたモードの動作に対して、曲げ損失とモード間隔のような他の損失メカニズムが利用される。その他の実施例も与えられる。
