SOP distributions.

Four vector beams with azimuthal variant state of polarization (SOP) generated with equation (8) are shown in four row panels, corresponding to (a–d). In each panel, different sketches of SOP trace on the Poincaré sphere marked by red line, SOP distribution in space and snap picture of SOP are demonstrated in order. Associated parameters in equation (8) for field generation are (a) , , (b) , , (c) , and (d) , , respectively.
