We demonstrate propagation, routing round bends and integrated detection of light on a deeply sub-wavelength scale in two-conductor metallic slot waveguides. Light with cross-section ∼ λ2/100 propagates ∼10λ at 850nm in good agreement with simulations.
Plasmonics is an exploding new field of science and technology in which the flow of light can be molded at the nanoscale using metallic nanostructures. This newly found ability is rapidly impacting every facet of optics and photonics and is enabling a myriad of exciting new technologies. Group IV photonics has also seen tremendous recent progress in the development of high performance light sources,...
We present the analysis and optimization of several basic elements for three-dimensional plasmonic slot waveguides. These elements are key building blocks for efficient routing of light that can be used in on-chip optical links.
