Abstract

In this work, we illustrate a simple approach of generating polarization singularities using cylindrical vector beams. We use a superposition of two free propagating Gaussian beams that modulated with optical vortices. The two cylindrical vector beams possess radially and azimuthally polarized components, respectively. By evaluating the Stokes parameters at the total beam focus of the total superimposed beam and tracking the null values of the Stokes parameters, various polarization singularities observed, such as star, lemon, spider-web, and high order polarization singularities.
