“…When the vector term in the wave equation defining the spin-orbit interaction is considered, the spectrum of the propagation constant is split. The splitting of levels due to the term ∇ε (spin-orbit interaction of photons) in lens-like media has been considered in several papers [49,50]. Spin-orbit interaction in waveguides can significantly change the energy spectrum, causing splitting and the removal of degeneracy of modes with different radial and azimuthal indices and polarizations [44,51,52].…”

Spin–orbit coupling and nonparaxiality effects during the propagation of vortex vector light beams in a cylindrical graded-index waveguide are investigated by solving the full three-component field Maxwell’s equations. Symmetry-breaking effects for left- and right-handed circularly polarized vortex light beams propagating in a rotationally symmetric graded-index optical fiber are considered. The mode-group delay in a graded-index fiber due to spin–orbit interaction is demonstrated. A scheme for observing the temporal spin Hall effect is proposed. It is shown that the relative delay times between vortex pulses of opposite circular polarizations of the order of 10 ps/km can be observed in graded-index fibers for high-order topological charges.

“…Spin-orbit interaction in these systems may significantly modify the energy spectrum causing the splitting and degeneracy lifting of modes [5,6]. These effects influence on the group delays of modes in optical waveguides [7,8] and become important in fiber optic communications with high carrying capacities and faster transmission rates.…”

A splitting of modes in a circular graded-index optical fiber is demonstrated by solving the full Maxwell equations using the perturbation analysis. It is shown that the degeneracy of vortex Laguerre-Gauss modes with distinct orbital angular momentum (OAM) and polarization (spin) but the same total angular momentum is lifted due to the spin-orbit (vector) and tensor forces. Numerical estimations of group delays of modes in optical fiber and frequency splitting in Fabry-Perot and ring resonators are presented.
