Complex 3D Vortex Lattice Formation by Phase-Engineered Multiple Beam Interference
Figure 9
Computational analysis of spiraling complex 3D vortex lattice formed in the presence of a perturbing beam and a fivefold multiple of relatively phase-shifted three beams leading to 15 + 1 noncoplanar multiple beam interference. (a)–(f) The intensity distributions of - planes while the value of “” is varied along the direction of propagation. The circled region (cyan) visualizes the spiraling vortex distribution, and the circled region (magenta) depicts how the energy gets coupled to the adjacent region, while the complex vortex lattice structure makes a whirling movement along the direction of propagation.
