Abstract

The experimental generation of vector Bessel beams of different orders with TE and TM polarizations is demonstrated in the optical frequencies domain and in free space by means of a Mach-Zehnder interferometer. For the zero order beams, these modes correspond to the well known azimuthal and radial polarization states, whereas higher order versions become vector vortices, thus carrying orbital angular momentum. The case of the lowest order TE and TM vector vortices, corresponding to a topological charge of l=1, is particularly interesting due to their off-axis location and the non-null intensity at the beam center, unlike the case of topological charges l>1. The polarization and angular momentum properties of these waves are thoroughly analyzed and discussed for different cases.
