Abstract
The spin-Hall effect can be used to modulate the linear polarization of light via the magneto-optical Kerr effect. A central area of an outer surface of an added layer atop a spin Hall material is illuminated while simultaneously passing a modulated electric current through the material, so that reflected light has a new linear polarization that differs from the initial linear polarization to a degree depending on the amplitude of the modulated electric current.
