Spin Hall effect of reflected light at the air-uniaxial crystal interface

Abstract

We theoretically and experimentally study the spin Hall effect of reflected light at an air-uniaxial crystal interface. The spin-dependent nanometer-sized displacements depend not only on the incident polarization and the incident angle of the light beam, but also on the orientation of the crystal optic axis. The experimental results are in perfect agreement with theoretical predictions for the vertical and horizontal polarization incidence.
