| 1. An optical device comprising:
a carbon nanotube, wherein surface plasmons exist on the carbon nanotube;
a substrate, wherein the substrate allows the coupling of photons with the surface plasmons to give rise to surface plasmon
polaritons;
a light source, wherein the light source provides photons to a first end of the carbon nanotube to give rise to the surface
plasmon polaritons, and photonic energy is radiated from the surface plasmon polaritons at a second end of the carbon nanotube;
and
a detector for detecting the photonic energy radiated from the surface plasmon polaritons.
