Figure 6: SOP and Poynting vector distributions of VVBs at elliptical eigenstates for θ = 45°.
From: Independent Manipulation of Topological Charges and Polarization Patterns of Optical Vortices
The first two columns show the measured SOP, as well as the orientation and ellipticity angles of polarization ellipses. The blue and red ellipses are the right- and left-handed polarization states, respectively. The third column shows the distribution of δ (x, y). The fourth column shows the displacements of focal spots on the Shack–Hartmann sensor plane. The last column shows the intensity patterns of light without passing through a polarizer. Associated parameters in each row are (a) (m1, m2) = (−3, −7), 
= −5, (b) (m1, m2) = (2, −2), 
= 0, (c) (m1, m2) = (4, 6), 
= 5, (d) (m1, m2) = (2, 4), 
= 3. All of the above parameters correspond to the same values of θ = 45° and Δφ = 0°.
