Abstract
A plasmonic waveguide structure with highly confined field and low propagation loss is disclosed. In selected embodiments, the structure has a sub-wavelength size dielectric core surrounded by stacks. Each stack includes multiple repeating, alternating metal layers and dielectric layers. The stacks operate in bandgap condition to render a highly-confined and low propagation loss waveguide structures that can be made using commercially available fabrication techniques.
