Dispersion-managed soliton control with narrow-bandpass filters and energy enhancement

摘要

The combination of narrow-bandpass optical filtering and self-phase modulation in a short fiber segment is here exploited to design a clock-independent all-optical regenerator of dispersion-managed solitons suitable for long-haul connections. The analytical approach and the numerical confirmations identify the optimal parameters of the regenerator that extend the transmission length of a single channel at 40 Gbit/s up to several thousand of kilometers.
