Complex 3D Vortex Lattice Formation by Phase-Engineered Multiple Beam Interference
Figure 1
Analysis of three noncoplanar beam interference patterns possessing a distribution of single-charged vortices. (a) Intensity distribution in - plane. (b) Intensity distribution with a lower threshold value in order to highlight the darker regions alone. (c) Phase profile. (d) The fork formation while the pattern is interfered with a plane wave launched at a large angle from the axis. (e) Intensity mesh plot. (f) Zero crossing plot (blue line: zeros of and green line: zeros of ).
