Propagation dynamics of entanglement: (a) Entanglement analysis of pure radial vector mode (black triangles) and the light field Inline graphic. Measured E as a function of kzz + ϕ (ϕ=−π/4) of the latter is marked by black circles filled according to the ratio between the Inline graphic and Inline graphic parts (see scale bar). Exemplary modes are shown as green insets. The black dashed curve represents the theoretical fit according to Equation (7). (b) Respective intensity IR,L of the Inline graphic (red fit, black filled diamonds) and Inline graphic (blue fit, black hollow diamonds) components of Inline graphic, oscillating out of phase.
