TL;DR: In this paper, the authors extend the concept of perfect optical vortex to the vector case and investigate its focusing properties in the high numerical aperture regime, showing that simultaneous phase encoding of orthogonal components can be realized by means of a 4 f imaging system incorporating a phase only liquid-crystal spatial light modulator whose director axis is rotated 45° with respect to the horizontal axis.

TL;DR: In this article, the effect of primary illumination properties on partially coherent Bessel mode vortex beams was investigated, and it was shown that a wide class of such vortex beams are coherent.
Abstract: We investigate the effect of primary illumination properties on partially coherent Bessel mode vortex beams. Based on the coherent mode representation, we show that a wide class of such vor...
