Abstract
We examine the spin-orbit coupling effects that appear when a wave carrying intrinsic angular
momentum interacts with a medium. The Berry phase is shown to be a manifestation of the Coriolis
effect in a noninertial reference frame attached to the wave. In the most general case, when both the
direction of propagation and the state of the wave are varied, the phase is given by a simple expression that
unifies the spin redirection Berry phase and the Pancharatnam-Berry phase. The theory is supported by the
experiment demonstrating the spin-orbit coupling of electromagnetic waves via a surface plasmon
nanostructure. The measurements verify the unified geometric phase, demonstrated by the observed
polarization-dependent shift (spin-Hall effect) of the waves.
