Half-plane diffraction in the case of Gaussian beams containing an optical vortex
Optics communications, 2000
In this paper the half-plane diffraction of the Gaussian light beam containing an optical vortex is examined. The analysis is performed analytically (scalar theory in the near field approximation). The stability and dynamics of the optical vortex within the diffracted wavefront is investigated. Some examples of diffraction by single slit are also presented.
Phase Singular Beams Generated by Holographic Grating: Characterization of Mueller Matrix
It is interesting to characterize Mueller matrix of a diffracting optical element used to transform a Hermite-Gaussian beam into vortex beams having phase singularity along its axis of propagation. Mueller matrices for vortices of topological charges +1, -1 and central order of diffraction have been characterized to quantify polarization introduced by the forked holographic grating.
