Summary form only given. Wavelength conversion based on cross gain modulation will play an important role in future wavelength-division multiplexed photonic switching networks. One of the major limitations of this technique is the induced chirp of the converted signal. Previous liable models determinate the refractive index, thus the chirp, from the gain values by Kramers-Kronig relations. The use of these models is usually difficult to integrate to a system performance evaluation. In this paper, we report a fast and easy implementable system modelled to study the amplifiers dynamic behaviour and in particular, the induced chirp. Additionally, its liability is confirmed experimentally, and by a Kramers-Kronig type model.
