Polarization domains and instabilities in nonlinear optical fibers

Abstract We study the possibility of generating polarization wall solitary waves in nonlinear optical fibers. These walls represent a polarization switching between two domains along the fiber where the state of polarization of two intense counterpropagating beams is a stable arrangement of the field. We show that the presence of spatiotemporal chaotic instabilities set an upper bound to the maximum fiber length (or input power).
