Numerical modelling of nonlinear ellipse rotation

Numerical modeling of nonlinear ellipse rotation has been made for an optical field propagating along a linear birefringent silica optical fiber. The kernel of this model comes from expressing the coupled field as a sum of two linearly polarized modes in the direction of the principal axes of the fiber. The developed model is suitable for the design of a big number of optoelectronic devices and let easily introduce the temporal dispersion effects.
