Fig. 2 | Experimental results for a structured light beam with linear longitudinal polarization variations along a helical transmission trajectory. (a), (b) Cross-sectional intensity profiles of the electric field at a propagation distance of z=15 mm for the simulation and experiment, respectively. (c) Cross-sectional intensity profiles (red and blue solid lines) extracted from (a) and (b) at the locations of white dashed lines. (d) The electric field component intensity and electric field intensity at different distances. (e), (f) Amplitudes and phase difference of electric field components Ex and Ey at different propagation distances. (g) Theoretical, simulated and experimental transmission trajectories.
