Název v původním jazyce

Numerical investigation of plasmonic directional couplers consisting of two dielectric slab waveguides separated with metallic claddings, in both linear and nonlinear regimes, has been performed, in terms of their geometrical as well as physical parameters.

Popis výsledku v původním jazyce

Plasmonic waveguide structures have found an increasing scientific interest in many areas of applications, due to their abilities to subwavelength light confinement and manipulations. Since the structures can strongly increase local fields, inherently-weak nonlinear optical effects can be significantly enhanced, and thus applied in many potential applications. Here we consider Kerr-type nonlinearity (i.e. intensity dependent refractive index, of both dielectric as well as metal components) and study nonlinear coupling between plasmonic slot waveguides. Based on our recent study, understanding the physics of such devices, comparing both linear and nonlinear performance, is a very important issue. We have studied switching characteristics of the relativeoutput power with respect to the level of nonlinearity. We discuss various physical mechanisms that limit the coupler performance and investigate possible optimization of geometrical parameters. Significant improvement of the coupler beh
