Spin angular momentum at the sharp focus of a cylindrical vector vortex beam by V.V. Kotlyar, S.S. Stafeev, A.M. Telegin

“…At the center of the focal spot near the optical axis, the field is right-handed elliptically polarized at m > 0, or left-handed elliptically polarized at m < 0, where m is the vortex charge. …”
