Tunable spatio-spectral Target Skyrmions and topological multiplexing

Andrew Forbes, Isaac Nape, Niladri Modak, Oussama Korichi, Pedro Ornelas, Robert Fickler

A single optical beam can carry three distinct Skyrmion numbers at different radii by coupling wavelength, space, and polarization.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We experimentally demonstrate the practicality of this approach by transmitting and receiving three distinct Skyrmion numbers encoded into a single topological field, for the first form of mode division multiplexing with Skyrmion topology.

C2weakest assumption

The non-separability of wavelength, space, and polarization can be engineered so that distinct Skyrmion numbers appear at different radii with negligible crosstalk and remain independently addressable after propagation.

C3one line summary

Three-degree-of-freedom spatio-spectral Skyrmions enable independent encoding of distinct Skyrmion numbers at different radii in one optical field, demonstrated experimentally as topological multiplexing.
