S. Trillo et S. Wabnitz, BLOCH WAVE THEORY OF MODULATIONAL POLARIZATION INSTABILITIES IN BIREFRINGENT OPTICAL FIBERS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(1), 1997, pp. 1048-1058
The modulational instability gain spectra, of an arbitrarily polarized
intense pump wave that experiences periodic nonlinear polarization ro
tation in a birefringent optical fiber, are derived by Floquet analysi
s. The predictions of the linearized analysis are confirmed by numeric
al simulations of the coupled nonlinear Schrodinger equations.
