Abstract
Method and apparatus for resonantly driving a nanowire waveguide a dielectric waveguide core placed close to the nanowire waveguide, so that energy couples from the dielectric waveguide to the nanowire waveguide. The resonant coupling can be achieved by selecting the dielectric waveguide and the nanowire to support modes having substantially the same frequency ω and same longitudinal propagation constant β.

A dual-waveguide system, comprising:
- a transparent dielectric waveguide;
- and
- a nanowire waveguide located in proximity to said dielectric waveguide, wherein said nanowire waveguide supports plasmon excitations and is resonantly coupled to said dielectric waveguide such that said dielectric waveguide resonantly drives plasmon oscillations on said nanowire waveguide.
A method for resonantly driving plasmon oscillations on a nanowire waveguide, comprising the steps of:
- driving a transparent dielectric waveguide at one end by a laser;
- and
- resonantly coupling said nanowire waveguide to said dielectric waveguide such that said dielectric waveguide resonantly drives plasmon oscillations on said nanowire waveguide.
A method for transferring energy from a dielectric optical waveguide to nanowire waveguide, comprising the steps of:
- driving a dielectric optical waveguide at one end by a laser;
- and
- resonantly coupling said nanowire waveguide to said dielectric waveguide such that said dielectric optical waveguide resonantly drives plasmon oscillations on said nanowire waveguide to transfer energy from said dielectric optical waveguide to said nanowire waveguide.
