Flexible Plasmonics on Unconventional and Nonplanar Substrates

Flexible plasmonics and metamaterials on polymeric and nonplanar substrates are demonstrated using nanostencil lithography. High-resolution fabrication with 10 nm accuracy is achieved at high throughput and low cost in a single fabrication step. Optical tuning is shown with mechanical stretching of the polymer substrate. Patterning of nanostructures on curved surfaces, including optical fibers, is demonstrated.
