Abstract in another language

We investigate the ultrafast time dynamics of magnetic waveguide-particle-plasmon polaritons in a magnetic photonic crystal. This magnetic mode consists of the antisymmetric localized charge oscillation in metallic cut-wire pairs. At the appropriate periodicity, strong coupling and polaritonic hybridization take place between the antisymmetric plasmon resonance and the excited photonic mode of the underlying slab waveguide. By varying the lattice period and the wire cross section of the structure, tailoring of the temporal dynamics of the magnetic polariton is possible. Simulations are in good agreement with third-order nonlinear autocorrelation function measurements and confirm extremely long dephasing times of the polaritonic system. Future applications could include all-optical control of optical magnetism.
