We demonstrate theoretically and experimentally that the circularly polarized light impinging on the sphere produces double charged optical vortex.

Abstract

We propose a radial polarizer based on light refraction on a transparent isotropic sphere. We demonstrate theoretically and experimentally that the circularly polarized light impinging on the sphere produces double charged optical vortex. The method is applied to generate optical vortices on a small scale using hollow micro-spheres produced by femtosecond laser in fused silica.
