Photonic skyrmion spin textures on meta-surface with the impact of loss and geometry

Year: 2024

Type: article

Abstract: Photonic skyrmions characterized by topological nontrivial electromagnetic textures have triggered enormous interest, exhibiting promising applications in optical information storage and precision metrology. The skyrmion generation on meta-surface is important for further developments of the skyrmion-based applications; however, it has received limited attention, with a particular lack of investigation into both intrinsic loss and geometry, which are crucial factors. Here, we demonstrate a photonic skyrmion spin lattice on a well-designed metallic nanohole array, examining the influence of inherent loss and geometry of meta-surface. In consideration of these factors, we show the broadened excitation wavelength tolerance for the photonic skyrmion spin lattices, which are also found to be robust against the inherent loss and wave-vector mismatch to a certain degree. This work provides new insights into the underlying mechanisms of the topological spin textures, as well as in developing applications in optical sensing and high-resolution imaging.
