Dataset for Topological bimeronic beams

This dataset supports the publication: Topological bimeronic beams, by Y.Shen in Optics Letters 2021 This Letter proposes a family of structured vector beams, bimeronic beams, that well characterize topological structures of bimeron (the quasiparticle homeomorphic to skyrmion). It is shown that the polarization Stokes vectors of bimeronic beams emulate bimeron structures, which are reconfigurable to form various topological textures by tuning mode parameters. The bimeronic beams unveil a new mechanism to transform diverse topological states of light, similar to the skyrmionic transformations among Néel-, Bloch- and anti-skyrmion types. Moreover, bimeronic transformations are more generalized to include skyrmionic transformations as special cases.
