Resumo

Nonlinear properties of metals based on the electronic collective ponderomotive interaction mechanism are modelled using the finite-difference time-domain (FDTD) method. The effects of such nonlinear behaviour are then studied simulating the plasmonic directional coupler formed by two dielectric (linear) cores and metallic claddings, and evaluating the change of the beat length for increasing peak-amplitude of the source field. It is demonstrated that switching controlled by the pulse energy is still possible even though the cores remain linear.
