Metafiber tips for generating optical skyrmions with subwavelength polarization features

Skyrmions, known for their intricate spin textures, are topological quasiparticles initially studied in particle and solid-state physics. They hold great promise as next-generation information carriers for data storage. Recently, their photonic counterparts—optical skyrmions—have emerged as topologically structured light forms with significant potential to revolutionize optical information technologies.
