Abstract

Full Poincaré beams, formed of all polarization states represented on a Poincaré sphere, have been intensively studied as an analogous topological quasiparticle, referred an optical skyrmion, in fundamental physics and advanced technologies. Néel-, Bloch-, and anti- skyrmions have been discovered in magnetic materials and liquid crystals, however, the generation of optical skyrmions is still an emerging topic in its infancy. In this study, we propose a robust and cost-saving system, formed simply of a single spatial light modulator with a self-referenced interferometric configuration, and waveplates, which enables the generation of some types of optical skyrmions.
