Schematic representation of the multiplexing principle. Binary hologram to generate the modes (a) \(L{G}_{1}^{2}\) and (b) \(L{G}_{2}^{-1}\), (left panel). The frequency value of each linear phase is properly chosen to shift the beam to the desired position, as shown on the right panel of (a,b). An example of a multiplexed hologram composed of the holograms shown on (a,b) is shown on the left panel of (c), whereas the overlapping of both first diffraction orders is shown on the right panel. Here, for the sake of clarity we only show the first and zero diffraction order, higher diffraction orders were omitted.
