Coriolis effect and spin Hall effect of light in an inhomogeneous chiral medium

Opt Lett. 2016 Jul 1;41(13):3070-3. doi: 10.1364/OL.41.003070.

Abstract

We theoretically investigate the spin Hall effect of spinning light in an inhomogeneous chiral medium. The Hamiltonian equations of the photon are analytically obtained within eikonal approximation in the noninertial orthogonal frame. Besides the usual spin curvature coupling, the chiral parameter enters the Hamiltonian as a spin-torsion-like interaction. We reveal that both terms have parallel geometric origins as the Coriolis terms of Maxwell's equations in nontrivial frames.
