Abstract

A set of couled nonlinear equations describing propagation of two polarization light modes inside optical fibers with stimulated Raman scattering are considered. Using a Lie group technique, the most general Lie algebra is derived for the two cases: with and without orthogonal Raman gain. The optimal set of reduced systems of ordinary differential equations for the case without orthogonal Raman gain is obtained.

Abstract

Two coupled nonlinear Schrodinger equations describing propagation of light pulses through nonlinear media with negative cross-phase modulation and different group-velocity dispersion regions for the two polarization modes are considered. Applying a Lie group technique, the most general Lie algebra and the corresponding Lie group of point symmetries permitted by the considered equations are derived. As a result, the optimal set of one-dimensional Lie algebras is obtained.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
