Takashige Omatsu (NYCU), and Atsushi Taguchi (Hokkaido Univ.) have demonstrated the nanofabrication of topological surface relief structures (chiral surface reliefs with a shape like a Möbius strip) in azopolymers using longitudinal electric fields and nano-scale circular polarization defects (C-point polarization defect) created by tightly focused optical skyrmions.
