Complex 3D Vortex Lattice Formation by Phase-Engineered Multiple Beam Interference
Figure 7
Computational analysis of complex 3D vortex lattices. 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) Phase profile. (d)–(f) Zero crossing plot (blue line: zeros of and green line: zeros of ). Under perturbation, the unfolding and shifting of the vortices are clearly visible and circled to identify the position.
