Deep diffractive optical neural networks for detecting skyrmionic topologies of light and their live training

Optical skyrmions are topological forms of structured light offering an unbounded encoding alphabet robust to perturbations. However, their practical use is limited by the absence of a topological detector, since states distinguished by their topological invariant, N, are not nec...

Broadening the color palette of optical skyrmions

Abstract Optical skyrmions have been demonstrated across many wavelengths, but so far only one at a time for a monochrome color palette. Now they are reported as broadband topologies across the entire visible spectrum, heralding white light skyrmions on-chip.
