摘要： 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 anistropic 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.

摘要： An apparatus for producing an inhomogeneously polarized optical beam from a homogeneously polarized input optical beam includes a first phase shifter, a second phase shifter, and one or more polarization beam splitters. The first phase shifter shifts at least one portion of a first part of the input optical beam by a first phase. The second phase shifter shifts at least one portion of a second part of the input optical beam by substantially the first phase. The one or more polarization beam splitters split the input optical beam into the first part and the second part and combine the phase shifted portion and substantially all other portions of the first part of the input optical beam with the phase shifted portion and substantially all other portions of the second part of the input optical beam to produce the inhomogeneously polarized optical beam.

摘要： 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 in accordance with embodiments of the present invention includes a first anisotropic material positioned adjacent to the first isotropic material in a substantially transverse manner relative to the path of the optical beam, wherein 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. The system may further include a second isotropic material and a second anisotropic material positioned adjacent to the second isotropic material in a substantially transverse manner relative to the path of the optical beam, wherein the second isotropic material and second anisotropic material are positioned downstream of the first isotropic material and first anisotropic material along the path of the optical beam, and wherein the second anisotropic material has a second alignment axis that produces one of a radially, azimuthally, and counter-rotationally polarized optical beam when substantially aligned with respect to the polarization axis of the optical beam. In addition, the present invention relates to an optical beam having an inhomogeneous polarization state in which the polarization rotates in a continuous and counterclockwise manner while traversing a circular path around the beam axis in a clockwise direction.
