Generation of Perfect Optical Vortices by Using a Transmission Liquid Crystal Spatial Light Modulator

Figure 1

Simulations of the intensity patterns and the phase structures for Bessel-Gauss beams and perfect optical vortices. (a)–(e) Intensity distributions of the BG beams with topological charges and , respectively. (k)–(o) and (p)–(t) Intensity distributions of POVs after the Fourier transformation of (a)–(e) for [mm] and [mm], respectively. (f)–(j) and (u)–(y) Phase profiles for the BG beams and the POVs, respectively. In the phase structures the black and white colors are corresponding to 0 and 2π. We used [nm] and [mm] here and for theoretical and numerical solutions shown in Figures 2, 3, and 4.
