Hopfions—higher-dimensional topological quasiparticles with sophisticated 3D knotted spin texturesdiscovered in condensed matter and photonic systems—show promise in high-density data storage andtransfer. Here, we present crystalline structures of hopfions lying in space-time constructed by spatiotemporally structured light. Practical methodologies using bichromatic structured light beams or dipolearrays to assemble 1D and higher dimensional hopfion lattices are proposed, and a technique for tailoringtopological orders is elucidated. Optical hopfion crystals constitute a new platform for high-dimensionaltopological information transfer.DOI: 10.1103/hh5s-cprt
