Effect of dispersion slope of highly nonlinear fibre on the performance of Self Phase Modulation based 2R-optical regenerator

In this paper we numerically investigate the effect of dispersion slope of the highly nonlinear fibre on the performance of Self Phase Modulation based 2R-optical regenerators. Our numerical study shows that the dispersion slope has a significant impact on the shape of the transfer function of the regenerator. The dispersion slope can therefore be used together with the dispersion value and the filter offset as an additional parameter to control the performance of the regenerator. It is also shown that a high dispersion slope can be beneficial in increasing the energy yield of the regenerator by a maximum of 23%. Dispersion slope is also helpful in reducing the effect of pulse-to-pulse overlapping.
