Abstract

The soliton self-frequency shift (SSFS) suppression first discussed in [1] has been achieved by the bandwidth-limited amplification. Here we propose a novel method of suppression of the SSFS in a fiber based systems. We have found, that efficient inhibition of the SSFS takes place when dispersion of the fiber changes its sign at the wavelength that lies near the spectral profile of the pulse. Namely, SSFS can be suppressed when the pulse propagates in the soliton dispersion region near the dispersion sign reversal (DSR) point, while weak wing of the pulse spectrum falls into the nonsoliton region.
