2D Exotic Optical Lattice via a Digital-Coding Circular Airy Beam

Optical lattices have been widely used from classic to quantum physics. The tunable and scalable fabrication of lattices would be of great significance in lattice-based multipartite applications. In article number 2300280, Junxiang Zhang, Li-Gang Wang, and co-workers propose and demonstrate the fabrication of a 2D exotic optical lattice via spatial crosstalk between a single structured circular Airy beam and a digital spatial mask. This flexible method can steer optical lattices with axis, axial symmetry, and even high orbital kaleidoscope structures, with potential applications in integrated and scalable optical and photonic devices.
