Propagation dynamics of entanglement: (a) Entanglement analysis of pure radial vector mode (black triangles) and the light field . 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
and
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
(red fit, black filled diamonds) and
(blue fit, black hollow diamonds) components of
, oscillating out of phase.
