Angular momentum of vector-twisted-vortex Gaussian Schell-model beams

Abstract

In this paper, we generalize a recently introduced class of partially coherent vortex beams known as twisted-vortex Gaussian Schell-model beams. Through the addition of spatially varying polarization, we created a beam whose angular momentum comes from three different sources: the underlying vortex order of the beam, the twist given to the random ensemble of beams, and the circular polarization of the beam. The combination of these angular momentum types allows for unprecedented control over the total angular momentum of the field and its transverse distribution.
