Complex 3D Vortex Lattice Formation by Phase-Engineered Multiple Beam Interference
Figure 6
Computational analysis of complex 3D complex vortex lattices. Taking the multiples of relatively phase-shifted three beams, where the numbers of interfering beams involved are, respectively, 6 + 1 beams (first column), 9 + 1 beams (second column), and 15 + 1 beams (third column). (a)–(c) Intensity distribution in - plane. (d)–(f) Intensity distribution with a lower threshold value in order to highlight the darker regions alone. (g)–(i) Intensity mesh plots.
