Abstract
A plasmonic waveguide is a promising candidate for nano-optical waveguides. First we review the principles and unique characteristics of plasmonic waveguides and compare them to conventional dielectric waveguides. Then, we demonstrate the propagation of a surface plasmon polariton along a metal slab waveguide. A symmetric metal slab waveguide simultaneously supports two opposite types of a surface plasmon mode similar to a metal film: short-range and long-range type modes. The strong field confinement of the short-range mode plays a crucial role in nano-optical waveguides. To avoid the trade-off between field confinement and propagation length, we demonstrate selective mode excitation and mutual mode conversion for superfocusing mediated by the long-range mode.
