摘　　要：Light with an optical orbital angular momentum(OAM)has attracted an increasing amount of interest and has found its way into many disciplines ranging from optical trapping,edge-enhanced microscopy,high-speed optical communication,and secure quantum teleportation to spin-orbital coupling.In a variety of OAM-involved applications,it is crucial to discern different OAM states with high fidelity.In the current paper,we review the latest research progress on OAM detection with micro-and nano-optical structures that are based on plasmonics,photonic integrated circuits(PICs),and liquid crystal devices.These innovative OAM sorters are promising to ultimately achieve the miniaturization and integration of high-fidelity OAM detectors and inspire numerous applications that harness the intriguing properties of the twisted light. 关键词：orbital angular momentum (OAM) optical VORTICES singular optics spatial light MODULATOR surface PLASMON POLARITON (SPP) HOLOGRAPHY PHOTONIC integrated circuit (PIC)
