摘要	An optical signal amplification device (200) comprises an optical amplifier (210) having a wavelength-dependent gain and an equalization device (100) optically coupled in series to the optical amplifier and having a wavelength-dependent transmission function that substantially equalize the gain of the optical amplifier, the equalization device comprising a waveguide Bragg grating having a substantially constant refractive index envelope and a chirp rate that varies in such a way as to obtain the wavelength-dependent transmission function.
其他摘要	一种光信号放大装置（200），包括具有波长相关增益的光放大器（210）和与光放大器串联光学耦合的均衡装置（100），并具有基本上均衡增益的波长相关传输函数。光放大器，均衡装置包括波导布拉格光栅，该光栅具有基本恒定的折射率包络和啁啾率，该啁啾率以获得波长相关的传输函数的方式变化。
