“…Thus, the modal solutions of the Maxwell equations in a GRIN media are the hybrid vector Laguerre-Gauss modes with the spin-orbit entanglement. The longitudinal field component can be expressed through the transverse field components, i.e., The propagation constant that is correct to the first-order nonparaxial term has the form [23]:…”

“…In [23], the splitting of modes in a graded-index optical fiber due to the spin-orbit interaction is shown by solving the Maxwell equations using perturbation analysis. Due to the axial symmetry of the fiber, the modes are (v + 1)-fold degenerated, and for a given value of principal number v = 2p + l, where p and l are the radial and azimuthal indices, the modes are degenerate by l. The modes are 2(v + 1)-fold degenerated if the polarization degeneracy of the modes is taken into account.…”

“…One of the goals of this review is to present a general picture of the polarizationdependent light transmission through optical fibers associated with the spin-orbit interaction. Recently, the effects of spin-orbit interaction in graded-index (GRIN) media have been of great interest [16,17,[21][22][23][24]. In [25][26][27][28], the propagation of polarized twisted light beams in a cylindrical graded-index optical fiber is investigated by solving the three-component field Maxwell equations.…”

Polarization is measured very often to study the interaction of light and matter, so the description of the polarization of light beams is of both practical and fundamental interest. This review discusses the polarization properties of structured light in multimode graded-index optical fibers, with an emphasis on the recent advances in the area of spin-orbit interactions. The basic physical principles and properties of twisted light propagating in a graded index fiber are described: rotation of the polarization plane, Laguerre–Gauss vector beams with polarization-orbital angular momentum entanglement, splitting of degenerate modes due to spin-orbit interaction, depolarization of light beams, Berry phase and 2D and 3D degrees of polarizations, etc. Special attention is paid to analytical methods for solving the Maxwell equations of a three-component field using perturbation analysis and quantum mechanical approaches. Vector and tensor polarization degrees for the description of strongly focused light beams and their geometrical interpretation are also discussed.

“…The paraxial approximation is usually used to study the propagation of light beams in a graded-index medium. Both ray and wave optics are applied to analyze the propagation of light in graded-index media [25][26][27][28][29][30][31][32][33][34][35][36][37][38]. In [39], the polarization-dependent Goos-Hanchen (GH) beam shift at a graded-index dielectric interface was examined.…”

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.
