Distribution of the azimuthal and radial components of the electric field. (a) in the absence and (b–f) in the presence of a vortex phase: (b) m = ±1, (c) m = ±2, (d) m = ±3, (e) m = ±4, (f) m = ±10. The radial component is denoted by brown lines and the azimuthal component is denoted by green lines.
