Symmetric metal slot waveguides with nonlinear dielectric core: bifurcations, size effects, and higher order modes
Wiktor Walasik, Alejandro Rodriguez, Gilles Renversez
We study the nonlinear waves propagating in metal slot waveguides with a Kerr-type dielectric core. We develop two independent semi-analytical models to describe the properties of…
