A racetrack resonator, several hundred nanometers in size and composed of plasmonic waveguides is presented. The wavelength spectrum of the plasmonic racetrack resonator has been numerically evaluated by using finite-difference time-domain method. As compared to the conventional plasmonic ring resonator, the output light intensity of the proposed plasmonic racetrack resonator is greater by almost one order of magnitude. The cavity mode of the plasmonic racetrack resonator has also been investigated.

Light Confinement

A novel type of plasmonic waveguide, consisting of graphene-coated nanowire integrated with triangle wedge substrate and the low-index dielectric gap, is introduced for nanoscale field confinement. Numerical simulations indicate that extremely compact light confinement and low propagation loss can be obtained owing to the strong coupling between the graphene-coated nanowire and the tip of the triangle wedge substrate. Meanwhile, the proposed waveguide is quite tolerant to practical fabrication error for other geometry parameters. The graphene-based waveguide in this study is a natural extension of dielectric waveguide, and may be helpful to the studies and applications of nanoscale optical devices such as photonic integrated circuits and biosensors.
