Controlling the Third-Harmonic Generation in a Metallic Photonic Crystal Coupled to a Waveguide — •Reinold Podzimski1, Matthias Reichelt1, Torsten Meier1, Tobias Utikal2, and Harald Giessen21Department Physik und CeOPP, Universität Paderborn, Warburger Str. 100, D-33098 Paderborn, Germany — 2Physikalisches Institut, Universität Stuttgart, D-70550 Stuttgart, Germany

The behavior of waveguide plasmon polaritons is studied employing ultrafast coherent control like schemes for a gold lattice coupled to a photonic waveguide, see Ref. [1] for the structure. Different models to describe the third-harmonic generation are presented and the resulting equations are solved numerically. [2] The calculations are compared to recent experimental data and show good agreement for the most prominent features in the time-integrated third order intensity. [3]
