STABILITY OF SOLITON PROPAGATION WITH SLIDING-FREQUENCY GUIDING FILTERS

We report on extensive experimental measurement of the allowable range of soliton pulse energies far stable, error-free propagation with sliding-frequency guiding filters, as a function of both filter strength and sliding rate, and on interpretative numerical analysis. The most important result is our discovery of an upper bound and related optimum value for the filter strength; at the optimum, the allowed range of pulse energies is nearly two to one.
