Figure 3: VVBs constructed by circularly polarized OAM eigenstates.
From: Independent Manipulation of Topological Charges and Polarization Patterns of Optical Vortices

The first column shows simulated SOP, where the black and blue marks represent linear and right-handed polarization states, respectively. The second and third columns show measured SOP with angles of orientation and ellipticity of polarization ellipses. The fourth column shows the transmitted intensity patterns of light behind a polarizer with its transmission axis in the x direction. The last column shows intensity patterns of light without passing through a polarizer. Associated parameters in each row are (a) (m1, m2) = (−1, 1), θ = 45°, and Δφ = 90°, (b) (m1, m2) = (3, 6), θ = 45°, and Δφ = 0°, (c) (m1, m2) = (3, 6), θ = 30°, and Δφ = 0°.
