Far-field radiation intensity and polarisation diagrams of (a) left-handed \(\left\vert {{{{\mathbf{\sigma }}}}}_{x}^{-}\right\rangle\) and (b) right-handed \(\left\vert {{{{\mathbf{\sigma }}}}}_{x}^{+}\right\rangle\) chiral dipoles, emitting pure RCP and LCP light, respectively. The arrows show the direction of the chiral dipole. c–f Far-field radiation intensity diagrams of the rotating \(\left\vert {{{{\mathbf{\sigma }}}}}_{z}^{\pm \pm }\right\rangle\) chiral dipoles with indicated handednesses and rotation directions. The colour map shows S3/S0 Stokes parameter which represents the handedness of the emitted light (values 1 and −1 correspond to RCP and LCP, respectively, defined from the point of view of the source). The arrows show the rotation direction of the chiral dipole. g Far-field radiation intensity and polarisation diagrams of right-handed “elliptically” polarised rotating chiral dipoles with varied phase difference between equal x- and y- components. The phase step is π/10.
