Properties of circularly polarized vortex beams
TLDR
The cylindrical decomposition of a circularly polarized vortex beam is decomposed into radial and azimuthal polarization and sheds light on the connections between orbital angular momentum and the spin of the light beams.Abstract:
The properties of circularly polarized vortex beams in cylindrical polarization bases are studied. A circularly polarized vortex beam is decomposed into radial and azimuthal polarization. With the proper combination of vortex charge and the handedness of the circular polarization, a focal field with an extremely strong longitudinal component as well as a flat-topped profile can be obtained. The cylindrical decomposition also sheds light on the connections between orbital angular momentum and the spin of the light beams.read more

Focusing of high numerical aperture cylindrical-vector beams.
TL;DR: It is shown that, in the particular case of a tightly focused, radially polarized beam, the polarization shows large inhomogeneities in the focal region, while the azimuthally polarized beam is purely transverse even at very high numerical apertures.

Intrinsic and extrinsic nature of the orbital angular momentum of a light beam.
TL;DR: Numerical calculations of both spin and orbital angular momentum are confirmed by means of experiments with particles trapped off axis in optical tweezers, where the size of the particle means it interacts with only a fraction of the beam profile.

Electromagnetic Diffraction in Optical Systems. I. An Integral Representation of the Image Field
TL;DR: In this article, an integral representation for the electromagnetic field in the image space of an optical system is obtained in the form of an angular spectrum of plane waves, which is closely related to that introduced by Luneberg (1944) as a vector generalization of well-known formulae of Debye (1909) and Picht (1925).
