We demonstrate that surface plasmon polaritons can be guided by nanometer-scale dielectric waveguides on top of a gold film. In a test experiment, plasmons were coupled to a curved radius dielectric stripe, which was wide and thick, using a parabolic surface coupler. This experiment demonstrates that using surface plasmon polaritons the scale of optoelectronic devices based on dielectric waveguides can be shrunk by at least an order of magnitude.
