Abstract

It is shown that the axis dislocation angle rotation of a circular polarized CP mode is an optical Magnus effect manifestation in a parabolic index low-mode fiber. The sum of the even and odd CP modes forms the circular polarized vortex. Arising additional phase (gamma) _b equals +/- (delta) (beta) ₂₁z of this vortex is a topological Berry phase. This phase appears due to a cycle changing axis direction of CP mode dislocation. The collection of CV and IV vortices forms the linear polarized LV vortex. The linear polarization azimuth of the LV vortex accomplishes the angle rotation - Rytov effect. In a step-index optical fiber CP mode may be considered as a superposition of stable CV and unstable IV vortices. At the fiber lengths equal to the half of a beat length, a CP mode forms a circular polarized edge dislocation, and at the lengths equal to the odd number of the quarter of a beat length a linear polarized pure screw dislocation is considered as a conversion of a spin momentum into a n orbital momentum. The conversion process of an angular momentum shows a dynamical unity of an optical Magnus effect and a topological Berry phase in the low-mode fiber fields. The physical nature of a topological Berry phase consists in the stimulation of a flow of a momentum density in the field of a CP mode arising due to the rotation of a linear wave polarization. The optical Magnus effect also stimulates a flow of the momentum density because of the rotation of the axis of linear polarized disclinations.
