All‐Optical Generation of Multifunctional and Tunable Longitudinal Magnetization Textures
Abstract: An all‐optical strategy for creating multifunctional and tunable longitudinal magnetization textures is demonstrated. This is realized by flexibly engineering the coherent interferences of two counter‐propagating azimuthally polarized vortex beams possessing on‐demand phase and amplitude encoding in a 4π optical microscopic setup. In doing so, one can access not only the regular longitudinal magnetization patterns including bright spheroid/needle, dark cage/channel, and bright‐dark alternating chain/comb, but also the exotic twisted counterparts with controllable number of turns, thereby making versatile magnetization on the targeted magneto‐optical media with integrated footprint possible. The presented research findings may hold tremendous potential in multidimensional high density and low energy consumption optomagnetic storage and photonics of spin, and beyond.
