Abstract
Coupled differential equations are derived that enable exact modelling of linear and nonlinear optical signal propagation including the perturbing linear effects of birefringence and mode-coupling. These linear effects give rise to pseudo-random evolution of the light polarisation of propagating waves. Numerical efforts are significantly reduced by using eigenpolarisations of the perturbed fibre as coordinates of the coupled differential equations. Evaluating these propagation equations for random Birefringence and Mode-Coupling, averaged values of the cubic nonlinear susceptibility of realistic, randomly perturbed fibres are calculated for four-wave mixing (FWM), self-phase modulation (SPM), and cross-phase modulation (XPM).
