Design, simulation, and experimental output of DFML implementing Eq. (11). (a–c) ML design phase maps for δx (a), δy (b), and θ (c)45. (d,g) Show ϕ+ and ϕ− phase maps, respectively, at 1310 nm. (e) Simulated intensity and phase of the propagated field under RCP polarization at z = 500 μm. (h) Simulated intensity and phase of the propagated field under LCP polarization at z = 500 μm. Brightness and colors refer to intensity and phase, respectively. (f,i) Measured intensity profiles of the generated structured beams with their associated interferograms. It is appreciable the different helicity in the OAM generation depending on the handedness of the circular polarization in input, since the two interferograms have opposite phase dislocations.
