“…In contrast, laser interference lithography is expected to be an emerging technique for the preparation of photonic crystals due to its simplicity, low cost, and environmental friendliness. Laser interference lithography was first applied in the late 20th century for the preparation of two- and three-dimensional photonic crystals [ 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 ]. Subsequently, people began to study this technique intensively, and through a large number of experimental analyses and numerical simulation optimizations, the preparation of photonic crystals by interferometric lithography gradually matured.…”

A microstructure determines macro functionality. A controlled periodic structure gives the surface specific functions such as controlled structural color, wettability, anti-icing/frosting, friction reduction, and hardness enhancement. Currently, there are a variety of controllable periodic structures that can be produced. Laser interference lithography (LIL) is a technique that allows for the simple, flexible, and rapid fabrication of high-resolution periodic structures over large areas without the use of masks. Different interference conditions can produce a wide range of light fields. When an LIL system is used to expose the substrate, a variety of periodic textured structures, such as periodic nanoparticles, dot arrays, hole arrays, and stripes, can be produced. The LIL technique can be used not only on flat substrates, but also on curved or partially curved substrates, taking advantage of the large depth of focus. This paper reviews the principles of LIL and discusses how the parameters, such as spatial angle, angle of incidence, wavelength, and polarization state, affect the interference light field. Applications of LIL for functional surface fabrication, such as anti-reflection, controlled structural color, surface-enhanced Raman scattering (SERS), friction reduction, superhydrophobicity, and biocellular modulation, are also presented. Finally, we present some of the challenges and problems in LIL and its applications.

The concept of the crystallization of a plasmonic vortex lattice (PVL), which is achieved through multiple beam interferences, has been experimentally demonstrated and theoretically investigated. The generation of these ordered sets involves the interference of six plasmonic sources with spin-dependent spiral phases that arise from the interaction between circularly polarized electromagnetic waves and chiral metallic structures. The described components are instrumental in vortex generation and lattice formation. We observed a gradual crystallization of PVL through a quantized process influenced by the array size and its topological properties. It is characterized by the order parameter that was defined in analogy to nematic crystals. We demonstrate the remarkable topological adaptability of the PVL lattices, along with their resilience to perturbations. This underscores their potential for diverse applications in optical communication and data storage.
