Generation of polarization vortices with a Wollaston prism and an interferometric arrangement.
A stable and simple interferometric arrangement based on a Wollaston prism is designed to combine two helical beams into a polarization vortex (PV). Different modes of helical beams are generated by a spatial light modulator (SLM). Due to the flexibility of the SLM, PVs with different kinds of intensity distribution, such as Laguerre-Gaussian modes and Bessel modes, are generated.
