Controllable oscillated spin Hall effect of Bessel beam realized by liquid crystal Pancharatnam-Berry phase elements
We demonstrate the oscillated photonic spin Hall effect (corresponding to circular or alternating spin current) by using the well-designed Pancharatnam–Berry phase optical elements fabricated in liquid crystal.
