Tunable Plasmonic and Hyperbolic Metamaterials Based on Enhanced Nonlinear Response

Figure 4

Normalized scattering response versus wavelength, for linear (blue line) and nonlinear (red line) dielectric core for the geometry in Figure 1(a). The electric field (left insets) and power flow (right insets) distributions are plotted on the plane at the higher-frequency Fano-like resonant peak (I) and cloaking dip (II) when linear operation is considered. The nonlinear plasmonic nanoparticle is illuminated with input intensity . The unstable branch of the nonlinear bistable response is plotted with a dashed red line.
