Spatiotemporal pulse weaving scalar optical hopfions
Chenhui Li, Sicong Wang, Xiangping Li
Abstract
Scalar optical hopfions weaved by nested equiphase lines in the shape of a toroidal vortex are theoretically designed and experimentally demonstrated. This category of hopfions manifesting as a spatiotemporally structured pulse propagating in space-time may enable encoding and transferring optical topological information in an additional (temporal) dimension.
