Moiré patterns can be described as the superposition of two or more periodic structures rotated by a relative twist angle. These patterns can be formed either from the vertical stacking of periodic lattices or the projection of two periodic lattices into the same horizontal plane. Photonic moiré lattices have exhibited broadband light trapping, optical chirality, and spatially-confined as well as long-range lasing. This talk will describe optical moiré phenomena in different plasmonic architectures. First, we will discuss how to design moiré nanostructures using scalable nanofabrication tools. Next, we will characterize and model their optical properties at different twist angles. Finally, we will integrate the plasmonic moiré nanopatterns with emissive materials and discuss potential applications of their short-range and long-range responses.
