The extent to which light can be focused with conventional optics is limited to λ/2 by the phenomenon of diffraction. Optical energy needs to be focused to less than 100nm to enable improvement and innovation in nanoscale applications. A novel lens structure to focus surface plasmons to a few tens of nanometer with high throughput is described here. This paper outlines the theoretical design and fabrication considerations of this novel plasmonic lens structure.
