Tailoring Ultra‐High‐Order Optical Skyrmions

As quasiparticles with topological spin textures, skyrmions have drawn considerable interest from the condensed matter and structured wave communities, offering potential for next‐generation high‐density, robust information technologies. Nevertheless, generating high‐order skyrmions remains a significant challenge, as they have not been reliably observed in any physical system. Here, the method is proposed to create and control ultra‐high‐order skyrmions (skyrmion number up to 400 th ) in a structured light system. The topological state transition between bimerons and skyrmions is also experimentally controlled, the transverse size of an arbitrary‐order skyrmionic beam is tailored independently of the topological number, and ensure the topological stability upon propagation. This work provides solutions for topologically resilient communication and memory, significantly enhancing information capacity.
