摘要：

It is found experimentally and theoretically that the second-order intermodulation product, namely composite second-order (CSO) distortion, is caused by the coupling of the gain tilt of an erbium-doped fiber amplifier with laser chirp. Er-Al-codoped fiber amplifiers have better linearity than Er-doped fiber amplifiers because the gain tilt of the former is smaller.
