Figure 1: Diagram and SEM image of fabricated fishnet structure. Here we experimentally demonstrate the first 3D optical NIM by directly measuring the angle of refraction from a prism made of cascaded ...
Figure 1: Schematics of the degenerate 4WM process on a thin nonlinear film. In this Letter, we experimentally demonstrate nonlinear optical negative refraction in thin metallic nanostructures. We use ...
