Generation of singular beams using electrically addressed liquid crystal spatial light modulator

In this paper, we demonstrate the ability of a spatial light modulator based technique of dual-phase modulation for the generation of vector-vortex beams which have non-zero radial and azimuthal indices. The generated vector-vortex beams hold both phase and polarization singularities. These beams have gained importance because of their association with the orbital angular momentum of light. They have applications in many areas of optics.
