Abstract
A system for converting the polarization state of an optical beam which propagates along a path from an initial polarization state into an inhomogeneous polarization state includes a first isotropic material and a first anisotropic material. The first anisotropic material is positioned adjacent to the first isotropic material in a substantially transverse manner relative to the path of the optical beam. The first anisotropic material has a first alignment axis that produces one of a radially, azimuthally, and counter-rotationally polarized optical beam when substantially aligned with respect to a polarization axis of the optical beam.
