New 2D material contenders show promise for nonlinear optics
Nonlinear optics, a study of how light interacts with matter, is critical to many photonic applications. 2D van der Waals superlattices, which comprise two stacked monolayer materials, provide an alternative to single-layer materials for engineering optical nonlinearities. These superlattices can significantly enhance the nonlinear optical responses of 2D materials by coherently increasing the light–matter interaction length and creating fundamentally new physical properties. The EU-funded ATOP project will leverage the potential of these materials for developing disruptive nonlinear photonic devices, such as on-chip optical parametric generation sources, broadband terahertz sources and high-purity photon-pair emitters. The resulting photonic systems could be highly valued in metrology, portable sensing and quantum communications.
