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.
