3D simulations of nanometric integrated optical circuits using surface plasmon polariton gap waveguide

Nanometric optical waveguide can be made by using the dependence of surface plasmon polaritons on the gap-width between two parallel metallic plates. This waveguide can be called surface plasmon polariton gap-waveguide (SPGW). The H and E-plane closed-type and E-plane open-type optical circuits that consist of SPGWs have been considered. Three-dimensional numerical simulations have been performed for the nanometric optical circuits that consist of straight, branch and bend SPGWs. Results show that optical circuits considered in this paper can perform guiding, branching and bending function of optical waves in the nanometric device.
