Abstract:
Generation of a cylindrically polarized light beam, and in particular, a hybrid-azimuthal-radial polarization beams, called HARP modes, generated from an input linearly polarized Gaussian beam using a spun optical waveguide device is taught. The HARP modes are comprised of hybrid-azimuthal polarization (HAP) and hybrid-radial polarization (HRP) superposition modes. These beams possess a non-zero local angular momentum density that is spatially varying and a zero total angular momentum.
