In this paper we propose, simulate and experimentally verify a novel and simple optical phase pre-emphasis method, which is capable of mitigating fiber nonlinearity in dense wavelength division mult-DWDM optical translation systems. In our simple method, each transmitted wavelength is modulated by a phase modulator driven by a periodic parabolic electric driving signal. Both of the simulations and experimental results verify that the proposed method can effectively mitigate the fiber Kerr nonlinearity.
