Figure 1 | Schematic diagram illustrating coherence singularities and formation of stable incoherent links in fluctuating speckled light.

Caption

a, Coherence characterization of fluctuating speckled light via the interference between different points and the central reference point. Zero degree of coherence indicates a coherence singularity. b, Incoherent topological structures are composed of multiple coherence singularities in the speckled light. In contrast, no stable intensity singularities can be observed in the instantaneous speckle light or its average intensity. c, Fluctuations in the intensity of the speckled light, averaging a uniform incoherent light field. d, Fluctuations in the amplitude and phase distribution.
