Generation of concentric perfect Poincaré beams
2019
We theoretically propose and experimentally verify a method to generate new polycyclic beams, namely concentric perfect Poincare beams (CPPBs), by using an encoded annular phase mask. The proposed beams consisting of multiple polarization structured fields can be simultaneously generated in one concentric mode, which are respectively mapped by fundamental Poincare sphere (PS), high-order Poincare sphere (HOPS), and hybrid-order Poincare sphere (HyPS). Moreover, the ring radius, numbers and polarization orders of the CPPBs at arbitrary positions on arbitrary PS are independently controlled. This work enriches the mode distributions of perfect vortex and introduces a new polarization degree of freedom, which has the potential to implement more information beyond the orbital angular momentum multiplexing in optical communication.
