The OAM-domain parallel gates and gates achieved by the three-layer structure. (A) OAM spectral shaping function for dual gates. (B) The entire matrix operator made up of two gates. (C) Dual gates tested with input superposed OAM states of and one-by-one. (D) and (E) Performances of parallel and gates as functions of OAM channels separation, respectively.
