Schematic illustration of the Fourier space spectrum of a sixfold nondiffracting beam. Beam component’s direction of propagation lies on the surface of a cone with an opening angle . Projection into the plane illustrates intensity peaks arranged on a ring with radius . Inserted one-dimensional modulated intensities correspond to equally colored arrows [cf. Eq. (1)].
Simulation of intensity and phase distribution of a kagome lattice. (a) Intensity distribution: details show the building blocks of a kagome lattice (upper: hexagon; lower: hour glass). (b) Phase distribution: magnified detail depicts three vortices with total topological charge of zero; dashed rectangle in the right picture implies building block.
Analysis of the KLB with . (a) Transverse intensity distribution: lines mark positions of the planes shown in (c) and (d). (b) Phase distribution: vortex positions marked by circle arrows, numbers indicate topological charge. [(c) and (d)] Longitudinal intensity distribution of the and intersection plane, respectively. Lines in (c) and (d) indicate the longitudinal beam center [cf. (a)].
