Abstract

　周囲光をフィードバックさせることにより半導体光増幅器の負帰還光増幅を行う光信号増幅装置において、半導体光増幅器とそれからの出力光を伝送する光ファイバとの結合構造をファイバグレーティングデバイスを用いて簡単且つ小型とすることができる光信号増幅装置を提供する。 　第１光ファイバグレーティングデバイスＦＧＤ１が第１半導体光増幅器１６の出力側に備えられて、第１半導体光増幅器１６に第１波長λ１の第１入力信号光Ｌ１が入力されると、第１波長λ１以外の光Ｌs1が第１ファイバグレーティングデバイスＦＧＤ１から反射されてその第１半導体光増幅器１６に直接再度入力されるので、半導体光増幅器１６とそれからの出力光Ｌout を伝送する第１光ファイバグレーティングデバイスＦＧＤ１との結合構造が簡単且つ小型となり、高速応答が可能となる。
