Fig. 6: Influence of the input Bessel beam on the spin-dependent oscillated separation.

From: Controllable oscillated spin Hall effect of Bessel beam realized by liquid crystal Pancharatnam-Berry phase elements

Fig. 6

The data points plot the transverse separation between the two spin states of cosine-like PSHE, where the corresponding theoretical curves are depicted by the solid lines. The data for different transverse wave vectors of the input Bessel beams are depicted by blue, orange and green colors, corresponding to the axicons with physical angles α = 0.5°, 1°, and 2°, respectively
