From: Experimental generation of arbitrary abruptly autofusing Circular Airy Gaussian vortex vector beams
Polarization distribution (front panels), intensity profiles (middle panels) and transverse phase (back panels) of the modes (a) \(\mathbf{U}_{1}\hat{\mathbf{e}}_R\), (b) \(\mathbf{U}_{-1}\hat{\mathbf{e}}_L\) and (c) \(\Psi _{1,-1}\), respectively. In (d) we illustrate schematically the autofocusing effect such beams experience upon propagation. Here, orange and green ellipses represent right and left circular polarization, while black lines symbolize linear polarization. For this example, a = 1, w = 0.1, \(r_0\) = 1, \(\nu _1=\nu _2=0\).
