Abstract
Methods and systems configured to assist with generating, controlling and detecting multiple orbital angular momentum (OAM) modes are described. An optical device for OAM multiplexing and/or demultiplexing (100), includes a metasurface (206B) for at least one of generating and receiving a plurality of OAM modes and one or more single-mode waveguides (110-1, 110-2, 110-3, …, 110-M) for coupling with a light source (102) or receiver (108) or a microwave or millimetre wave source or receiver. The metasurface spatially matches one or more of the plurality of OAM modes to a corresponding one or more of the single-mode waveguides.
