Nanofocusing on gold planar nanotip arrays
Nanofocusing of incident light in the visible and infrared regions is achieved using tapered metallic nanostructures (TMNSs). Illumination under 633 nm excitation produces a very small (∼40 nm in the x-direction), very bright spot with a specific geometry, demonstrating near-field nanofocusing of th...
