By using metallic nanostructures as a bridge

between photonics and electronics, one plays to

the strengths of the metallic nanostructures

(concentrating fields and subwavelength

guiding), the dielectric waveguides (low loss

information transport) and the nanoscale

electronic components (high speed information

processing).
