Geometrodynamics of polarized light: Berry phase and spin Hall effect in a gradient-index medium

Open access

Abstract

We review the geometrical-optics evolution of an electromagnetic wave propagating along a curved ray trajectory in a gradient-index dielectric medium. A Coriolis-type term appears in Maxwell equations under transition to the rotating coordinate system accompanying the ray. This term describes the spin-orbit coupling of light which consists of (i) the Berry phase responsible for a trajectory-dependent polarization variations and (ii) the spin Hall effect representing polarization-dependent trajectory perturbations. These mutual phenomena are described within universal geometrical structures underlying the problem and are explained by the dynamics of the intrinsic angular momentum carried by the wave. Such close geometro-dynamical interrelations illuminate a dual physical nature of the phenomena.

TL;DR

This review develops a unified geometrical-optics description of spin-orbit coupling of light in a gradient-index dielectric, where the Berry phase and spin Hall effect are mutual consequences of a Coriolis-type term in the ray-accompanying frame. It shows that polarization evolution and polarization-dependent ray deflection are governed by Berry connection/curvature and by conservation of total angular momentum.

Key findings

  • The Berry phase and spin Hall effect of light are two sides of the same spin-orbit interaction: the Berry phase describes the trajectory’s effect on polarization, while the spin Hall effect describes polarization’s reaction on the ray trajectory; both follow from a single spin-orbit Lagrangian.
  • The Berry curvature takes the form of a topological monopole in momentum space and equals \(F = t\) on the unit \(t\)-sphere, indicating unit Gaussian curvature; the Berry phase for a cyclic evolution equals the solid angle \(\Theta\) cut by the loop on the \(t\)-sphere, up to a \(2\pi\) frame-rotation difference.
  • The spin Hall effect adds a helicity-dependent topological term to the ray equations, producing a transverse deflection orthogonal to both the wave momentum \(p\) and the inhomogeneity gradient \(\nabla n\); its magnitude is estimated as the wavelength \(\lambda\) for a complete \(2\pi\) turn of the propagation direction, and the splitting between right- and left-hand circularly polarized beams is \(\Delta = 2\delta r_0\).
  • For a helical ray in a cylindrically symmetric medium, the Berry phase grows linearly with propagation distance and rotates the polarization ellipse uniformly; the spin Hall displacement is directed along the binormal and accumulates over repeated cyclical trajectories.

Methods

  • Theoretical review using short-wavelength geometrical optics for a monochromatic electromagnetic wave in a smoothly inhomogeneous isotropic dielectric, with small parameter \(\mu\) comparing wavelength to medium inhomogeneity scale.
  • Maxwell equations are projected onto the plane transverse to the ray, transformed to a ray-accompanying rotating coordinate frame, and diagonalized in the circular-polarization basis; the resulting Coriolis term is treated to first order in \(\mu\).
  • The analysis uses Berry connection/curvature, Jones-vector and Stokes/Poincaré representations, Euler-Lagrange ray equations, and a worked example of a helical ray in a cylindrical gradient-index medium.

Limitations

  • The paper states that it considers only the spin-redirection Rytov–Vladimirskii–Berry phase in inhomogeneous media and does not cover generalizations to step-index interfaces, anisotropic media, or higher-order states of light carrying orbital angular momentum.
  • It notes that geometrical optics is rigorously inapplicable in single-mode waveguides, although the polarization evolution and Berry phase of waveguide modes obey the same geometrical formalism.
  • It states that the spin Hall displacement is typically much smaller than the width of a paraxial optical beam, though observable because beam centroids can be measured with subwavelength accuracy; it also notes that the Imbert–Fedorov shift cannot generally be described within the Berry-phase formalism because of non-adiabatic evolution at sharp interfaces.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
