Plasmon–plasmon interaction: controlling light at nanoscale

Yu A Akimov and H S Chu



This paper investigates the effect of the locally induced bulk plasmon resonance on light guiding of a plasma-like medium. It is demonstrated that, by inducing or suppressing the bulk plasmon resonance, one can manipulate the light propagation. This concept is then employed for a hybrid dielectric-loaded plasmonic waveguide with the aim to efficiently control the surface plasmon polaritons with a highly doped silicon as an active material. The proposed approach is shown to have a high potential for nanoscale light manipulation and development of a fully CMOS-compatible electro-optical plasmonic modulator.
