“…[24][25][26] In recent years, the structured light of the vortex beam has been introduced to prepare optical vortex lattices, which carry the orbital angular momentum of photons within each array and have an additional degree of tunability to the lattice structure. Using the vortex beam involved diffraction, nonlinear and coherent processes, the lattice has been created, of which the beam arrays were determined and controlled by the shape of the diffraction optics [27][28][29][30][31][32] or by the orbital angular momentum of the vortex beam. [33][34][35][36][37][38] Here, we propose an alternative scheme to engineer 2D optical lattices utilizing a structured circular Airy beam (CAB) and a digital spatial mask.…”

Optical lattices have been widely used from classical to quantum physics. The tunable and scalable fabrication of lattices would be of great significance in lattice‐based multipartite applications. This work demonstrates first that a circular Airy beam (CAB), which has the peculiar properties of self‐healing and abrupt autofocusing, can be used to generate two‐dimensional (2D) optical lattices in propagation when encoded by a programmable spatial mask, resulting in the formation of large‐scale and tunable optical lattices with both axis and axial symmetry, and even high‐orbital kaleidoscope shapes. The efficient diffraction of CAB during the spatial crosstalk with the mask enables the realization of tunable lattices with rich periodicity and complexity. The study shows a flexible method to manipulate lattices with large‐scale and versatile structures for potential applications in integrated and scalable optical and photonic devices.
