Abstract

In this paper, we show that the distortion of the amplifier gain such as gain flattening with respect to wavelength, can be accounted for by treating the amplifier as cascaded optical filters with gain. The gain shape of each filter section is calculated based on the output power of the previous section and the local carrier density, wavelength dependent gain peak location and wavelength dependent saturation power
