Abstract

Fields containing polarization singularities normally do not host all the Stokes vortices. For example, fields with $S_{12}$ Stokes vortices ($C$-points, $V$-points) in general do not contain $S_{23}$ Stokes vortices (Poincare vortices). In this paper, we demonstrate for the first time, to the best of our knowledge, synthesis of a structured field that hosts all three Stokes vortices, namely, $S_{12}$, $S_{23}$, and so far unexplored $S_{31}$ Stokes vortices. Only $S_{12}$ Stokes fields that host $C$-points and $V$-points have been experimentally realized by many research groups. Generation of $S_{23}$ Stokes fields that contain Poincare vortices have been proposed earlier but not experimentally demonstrated so far. There are no reports on the generation of $S_{31}$ Stokes field containing the third set of Stokes vortices.
