Over the past decades, orbital angular momentum (OAM) has attracted great interest due to its helical phase characteristics. It has been proved that plane spiral OAM (PSOAM) waves have a potential in azimuthal pattern reconfiguration. PSOAM waves could be termed as a special form of OAM wave, which avoids the inconsistency of the divergent angles for different OAM waves. However, from a practical point of view, such a PSOAM-based pattern reconfiguration scheme badly needs a compact high-purity…
