英文摘要	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.
