Schematic representation of the investigated field with a z-dependent degree of entanglement. (a) Concept, (b) phase change of the radial/azimuthal beam (top/bottom) relative to the initial phase, (c) absolute value of the relative phase difference between the radial and azimuthal beam, (d) change in polarization upon intensity (top) with the corresponding degree of entanglement E (bottom) for superimposed counter-propagating radial and azimuthal vector beams, all depending on the propagation distance z (k_zz∈[0,π]). Further, b and c include the respective polarization distributions per distance.
