Prof. Takashige Omatsu group at Chiba University has demonstrated the generation of multicolor (523, 605, 637, and 719 nm) optical quasiparticles (bimerons and skyrmions with topologically protected polarization textures) from a diode-pumped Pr3+-doped fluoro-aluminate glass (Pr 3+: WPFG) fiber. This robust and cost-saving system efficiently produces Bloch-, Néel-, and anti-quasiparticles with high mode purity. In particular, the green optical quasiparticles will have the potential to explore many applications in materials science and biotechnologies.
