ABSTRACT:
An optical amplifier has an optical amplifying medium, a pump light source outputting pump light, and a first optical coupler for supplying the pump light to the optical amplifying medium. A probe light source outputs probe light having a wavelength included in an amplification band, a second optical coupler supplies the probe light to the optical amplifying medium, and detectors detect the powers of input signal light and the probe light, respectively. A control unit controls the power of the probe light according to outputs from the detectors. This structure makes it possible to provide an optical amplifier which can reduce the wavelength dependence of gain.
