光放大装置
摘要：
本发明提供一种光放大装置，对于对波长互不相同的多个信号光进行多路复用而得到的信号光，即使不测量每个波长的信号光功率，也能抑制增益的波长依赖性。光放大装置(100)包括：可变斜率均衡器(11)，该可变斜率均衡器(11)对放大信号光施加基于直线式损耗斜率而得的损耗，并能对损耗斜率的倾斜即损耗斜率值进行变更；以及斜率控制部(22)，该斜率控制部(22)对可变斜率均衡器的损耗斜率值进行控制。
摘要（英）：

Provided is an optical amplifier that is capable of suppressing the wavelength dependency of a gain without having to measure the signal light power for each wavelength for signal light in which a plurality of signal light rays having mutually differing wavelengths are multiplexed. An optical amplifier (100) according to the present invention is provided with: a variable tilt equalizer (11) that suppresses the wavelength dependency of a gain by giving a loss according to a rectilinear loss tilt to amplified signal light and that is capable of changing a loss tilt value, which is the slope of the loss tilt; and a tilt control unit (22) for controlling the loss tilt value of the variable tilt equalizer.
