Abstract

Modulational Instability (MI) is one of the most beautiful nonlinear effects in optical fibers. MI causes the exponential amplification of small temporal perturbations of the cw pump radiation . In spectral domain Stokes and anti-Stokes components are exponentially amplified at the frequency shifts determined by pump intensity [1]. Depending on the polarization properties of optical fibers various types of MI can be observed both in the regions of positive and negative fiber group velocity dispersion (GVD) [2].
