✦ Synopsis
The nonlinear interaction of two laser beams in normally dispersive highly birefringent optical fibers leads to a large set of fascinating physical effects Ž . such as modulational instability MI and stimulated Raman scattering Ž . SRS . These two nonlinear phenomena have a positive role as a mechanism for the generation of short optical pulses and represent a drawback in fiber-optics transmissions. Indeed, we will show that an induced process of modulational instability may be exploited for the generation of THz train of vector dark solitons. The technique of frequency-resolved optical gating is used to completely characterize the intensity and phase of the dark soliton trains. On the other hand, we shall discuss control processes for MI and SRS in birefringent optical fibers. In particular, we analyze experiments showing that with dual-frequency, orthogonal polarization pumping one may achieve the simultaneous suppression of modulational instability and substantial reduction of stimulated Raman scattering.
