Abstract

　サンプリング用光パルス発生部は、監視対象の光信号を変調しているデータ信号のクロック周期の整数倍に対して所定オフセット時間だけ異なる周期を有するサンプリング用光パルスを出射する。光サンプリング部は、電界吸収型光変調器を用いて監視対象の光信号をサンプリングする。前記電界吸収型光変調器は、光路を伝搬する光に対する吸収率が電界の大きさに応じて変化する特性を有している。監視対象の光信号は、前記電界吸収型光変調器の２つの光端子のうちの一方に入射される。また、前記２つの光端子のうちの他方の光端子には、サンプリング用光パルスを光カプラを介して入射させる。このサンプリング用光パルスが入射したときに生じる前記電界吸収型光変調器の相互吸収飽和特性により前記監視対象の光信号に対する吸収率を低下させて前記監視対象の光信号をサンプリングすることにより、前記２つの光端子のうちの他方の光端子から前記光カプラを介して光パルス信号を出射させる。
