Abstract: The presentation on topological charge distributions in stochastic optical fields concludes that by using a combination of speckle fields one can produce inhomogeneous vortex distributions that allow both analytical calculations and numerical simulations. One-dimensional topological charge density causes Gaussian decay obeys (modified) diffusion equation and diffusion parameters related to coherence areas. Two-dimensional topological charge density results in the same diffusion behaviour, while additional nonlinear behaviour may be explained by drift mechanisms.
