- Abstract
- We present a method for producing laser beams of nonuniform polarization where the polarization direction
rotates on a trajectory about the beam propagation direction. Our method uses a Sagnac interferometer that
incorporates a spatial light modulator to combine beams that possess oppositely charged phase vortices in
order to achieve the desired polarization vortex. We demonstrate the utility of our method by producing polarization
vortices characterized by a fractional index, and we compare the results with calculations of the
expected fields. (literal)
