Abstract
【解決手段】光増幅装置1の制御方法は、光増幅部13及び光減衰部12が集積された半導体チップ11において、光減衰部に第1の電圧を印加し、光L1が光減衰部12に入力されたときに光減衰部12に流れる電流値IMに基づいて光L1の強度を演算し、この演算の結果に基づいて設定された第2の電圧を光減衰部12に印加し、光増幅部13を駆動させる制御を行う。この制御方法では、光増幅部13から出力された出力光の強度を検知し、出力光の検知結果に基づいて光増幅部13をフィードバックにより制御してもよい。

Description
最初に本願発明の実施形態の内容を列記して説明する。本願発明の一実施形態は、光増幅部及び光減衰部が集積された半導体チップを備える光増幅装置において、光減衰部に第1の電圧を印加し、光が光減衰部に入力されたときに光減衰部に流れる電流値に基づいて光の強度を演算し、演算の結果に基づいて設定された第2の電圧を光減衰部に印加し、光増幅部を駆動させる制御をなす光増幅装置の制御方法である。
以下、添付図面を参照して、本発明の好適な実施形態について詳細に説明する。なお、以下の説明において、同一要素又は同一機能を有する要素には、同一符号を用いることとし、重複する説明は省略する。
図1は、本実施形態に係る光増幅装置の使用例を示す模式図である。図1に示されるように、光増幅装置1は、光送信器2と光受信器3との間に設けられている。光増幅装置1は、コネクタ4aが取り付けられた光ファイバ4と、コネクタ5aが取り付けられた光ファイバ5とを有する。コネクタ4aは、例えば光送信器2に接続される光ファイバ6のコネクタ6aに接続されるように設けられる。コネクタ5aは、例えば光受信器3に接続される光ファイバ7のコネクタ7aに接続されるように設けられる。したがって、例えば光増幅装置1には光ファイバ4,6を伝搬する光が入力される。また、光増幅装置1は、例えば光ファイバ5,7を伝搬する光を光受信器3へ出力する。
