Polarization of light and topological phases
TLDR
In this article, a survey and analysis of recent work on topological phases with polarization of light is presented, which has revealed several counterintuitive features of such phase shifts such as 2 nπ anholonomies, nonlinear and discontinuous behaviour originating from high singularities, peculiar spectral dependence, etc.About:

Optical spin-to-orbital angular momentum conversion in inhomogeneous anisotropic media
TL;DR: An optical process in which the spin angular momentum carried by a circularly polarized light beam is converted into orbital angular momentum, leading to the generation of helical modes with a wave-front helicity controlled by the input polarization is demonstrated.

Spin-orbit interactions of light
TL;DR: In this paper, the authors provide an overview of the fundamental origins and important applications of the main spin-orbit interaction phenomena in modern optics that play a crucial role at subwavelength scales, including spin-Hall effects in inhomogeneous media and at optical interfaces, spindependent effects in non-paraxial (focused or scattered) fields, spin-controlled shaping of light using anisotropic structured interfaces (metasurfaces).

TL;DR: Karimi et al. as mentioned in this paper showed that a plasmonic metasurface comprising an array of nano-antennas can couple spin-to-orbital angular momentum at thickness much smaller than the wavelength of the light with an efficiency of around 3%.

Polarization noise suppression in retracing optical fiber circuits.
TL;DR: A novel scheme is proposed in which the presence of a Faraday rotator in a retracing fiber-optic circuit allows the complete, passive, and universal compensation of any birefringence change occurring in the fiber.

Geometrical phase and amplitude accumulations in dissipative systems with cyclic attractors.
Cun-Zheng Ning,Hermann Haken +1 more
TL;DR: It is shown that the geometrical (Berry) phases discovered in Hamiltonian systems can also be defined as resulting from parallel transportation of vectors for nonlinear dissipative systems with cyclic attractors.

A geometric-phase interferometer
TL;DR: In this article, an interferometer operating purely on the geometric phase is described, and the optical paths traversed by the two beams in this interferometers are always equal.

Berry phases and unitary transformations
TL;DR: In this article, the authors define Berry phases for spin, which are derived from the eigenvalues of the unitary operator for the product of these rotations and the angle of the product rotation is shown to be the solid angle enclosed by the loop.
