Soliton phase jitter control by use of super-Gaussian filters

By theoretical calculating, we derive the theoretical results of soliton phase jitter in soliton transmission systems using super-Gaussian filters, and we demonstrate that soliton phase jitter can be fully suppressed by super-Gaussian filters. By theory and computer simulations, we show that super-Gaussian filters are more effective in reducing phase jitter than conventional filters without sacrificing the signal-to-noise ratio.
