Metafiber tips for generating optical skyrmions with subwavelength polarization features

Nov 25, 2024 (Nanowerk Spotlight) 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...
