Noordam, M.L. (author)In this thesis, we explore the interaction between multiple optical light fields. Although these light fields can interfere with each other in a vacuum, actual interaction can only occur in a medium. This interaction can be amplified in materials with nanoscale dimensions such as a monolayer of WS2 and metallic nanostructures. The shapes of...doctoral thesis 2023
