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.
