Об эффективном уравнении эволюции нелинейного импульса в случайно--анизотропной среде

Колоколов И. В., Турицын К. С.
Propagation of a light pulse through a weakly inhomogeneous optical fiber is analyzed. The nonlinear envelope equation describing the evolution of polarized pulses is determined by statistical properties of inhomogeneities in the optical fiber. The isotropic Manakov system of equations is shown to be applicable in the presence of high-frequency small-scale defects in the fiber. In the presence of only large-scale inhomogeneities, the signal dynamics are described by an anisotropic system of equations.
