Complex 3D Vortex Lattice Formation by Phase-Engineered Multiple Beam Interference

Figure 2

Simulation of complex 2D vortex lattice intensity profile possessing a distribution of higher-order topological charged as well as single charged vortices. Taking the multiples of relatively phase-shifted three beams, the numbers of interfering beams involved are, respectively 6 beams (first column), 9 beams (second column), and 15 beams (third column). (a)–(c) Intensity distribution in 𝑥-𝑦 plane. (d)–(f) Intensity distribution with a lower threshold value in order to high light the darker regions alone. (g)–(i) Intensity mesh plots.
