Reduction of soliton interactions by sliding-frequency second-order Butterworth filters.
The reduction of the soliton interaction by use of optical sliding-frequency second-order Butterworth filters is studied numerically. It is found that the second-order Butterworth filters can reduce the soliton interaction more effectively than Fabry-Perot filters or third-order Butterworth filters because the secondorder Butterworth filter induces larger frequency chirping on the soliton, compressing it as it propagates in the fiber after the filter.
