  Optical vortex beam,each photon of which carries orbital angular momentum,has attracted a great deal of attention in recent years.One of the reasons for its wide research is its potential to achieve high capacity density,high spectral efficiency,and fast configurability in future optical interconnects [1].Many ways to generate vortex beam have been proposed including spatial light modulator,spiral phase plate,metasurfaces and photonic crystal laser [2].Either way,these methods are either system complexed or not at the communication wavelength.
