Ioan-Augustin Chioar, Christina Vantaraki, Merlin Pohlit, Richard M. Rowan-Robinson, Evangelos Th. Papaioannou, Björgvin Hjörvarsson and Vassilios Kapaklis Steering light with magnetic textures Appl. Phys. Lett. 120 (2022-04-27 17:05:14), 032407 DOI: 10.1063/5.0074391 We study the steering of visible light using a combination of magneto-optical effects and the reconfigurability of magnetic domains in yttrium-iron garnet films. The spontaneously formed stripe domains are used as a field-controlled optical grating, allowing for active spatiotemporal control of light. We discuss the basic ideas behind the approach and provide a quantitative description of the field dependence of the obtained light patterns. Finally, we calculate and experimentally verify the efficiency of our magneto-optical grating. |
