摘      要：The orbital angular momentum(OAM)of light has been shown to be useful in diverse fields ranging from astronomy and optical trapping to optical communications and data ***,one of the primary impediments preventing such applications from widespread adoption is the lack of a straightforward and dynamic method to sort incident OAM states without altering the ***,we report a technique that can dynamically filter individual OAM states and preserve the incident OAM states for subsequent *** the working principle of this technique is based on resonance,the device operation is not limited to a particular *** states with different wavelengths can resonate in the resonator without any additional modulation other than changing the length of the ***,we are able to demonstrate a reconfigurable OAM sorter that is constructed by cascading such optical *** approach does not require specially designed components and is readily amenable to integration into potential applications.
