Pancharatnam-Berry phase reversal via opposite-chirality-coexisted superstructures
文献摘要：
Recently discovered reflective Pancharatnam-Berry phase(PB phase)from chiral anisotropic media(e.g.,cholesteric liquid crystal,CLC)has aroused great interest in the emerging frontier of planar optics.However,the single chirality of common CLCs results in the intrinsic limitation of the same spin-selective PB phase manipulation,which means the reversal of the input spin cannot realize the conjugated PB phase.In this work,an innovative scheme based on opposite-chirality-coexisted superstructures is proposed to simultaneously modulate orthogonal circular polarization and get PB phase reversal.Through refilling CLC into a washed-out polymer network with opposite chirality and delicate photo-patterned structures,reflective optical vortex(OV)with opposite topological charges and vector beams with conjugated spiral PB phases are efficiently generated depending on the incident polarization.Furthermore,OV holograms are encoded to reconstruct polarization-selective OV arrays,indicating the strong capability of such opposite-chirality-coexisted anisotropic media.This work provides a new compact platform for planar optics,and sheds light on the architectures and functionalities of chiral superstructures.
