We analyze the interplay between surface plasmon polaritons and Rayleigh anomalies in the spectra of two-dimensional metallic superlattices and compare the measurements with a numerical modelling of these structures using a Fourier modal method.
In order to tune the coupling strength and to tailor the dephasing, a sample with varied grating period to shift the magnetic resonance in and out of the laser excitation is fabricated. The exact resonance of the magnetic photonic crystal with respect to the laser spectra is shown.
Coherent control on the nanoscale has gained a lot of interest in the last years in theory and experiment. In this work we present a new method of coherent control of the material polarization in a nanoplasmonic system within a few tens of femtoseconds. We show that the polarization can be turned off completely at any desired time after excitation and it remains off.
Vertical meanders composed of a continuous metallic film with rectangular profiles are promising for realizing frequency and spatial filtering functions due to the efficient electromagnetic coupling properties. This paper investigates numerically the band structures and transmission spectra of the meanders under variation of structural parameters as periodicity P and corrugation depth T. The numerical...
We present time-resolved nonlinear optical measurements on polaritonic states in metallic photonic crystals. The femtosecond time dynamics of the polariton are tailored by an interferometric three-pulse pump-probe technique.
Interaction of localized plasmons and propagating waveguide modes leads to strong coupling and polariton formation. These polaritons are the basis of nanoplasmonic effects in linear and nonlinear optics. Experiments, theory, and applications are presented.
We investigate the dephasing time of particle plasmons coupled to dielectric waveguide modes and observe a prolonged plasmon dephasing and temporal beats when changing the coupling strength between the waveguide modes and the plasmon resonance.
