Plasmonic systems involve interfaces containing both a metal and a dielectric material. In an effort to investigate the scaling of the nonlinear response of the surface plasmon polariton at a metal/dielectric interface, where both the metal and the dielectric present optical nonlinearity, we introduce a figure-of-merit that quantifies the contribution of the metal and the dielectric to the nonl...

We demonstrate experimentally that a one-dimensional photonic crystal with a homeotropic nematic liquid crystal defect behaves as a polarization-sensitive nonlinear all-optical device. We study statics and dynamics of the nonlinear optical response for linearly and circularly polarized beams and show enhanced light sensitivity and polarization self-modulation effects.

We study the linear and nonlinear optical properties of hybrid metallic-dielectric plasmonic gap nanoantennas. Using a two-step-aligned electron beam lithography process, we demonstrate the ability to selectively and reproducibly fill the gap region of nanoantennas with dielectric nanoparticles made of lithium niobate (LiNbO3) with high efficiency. The linear optical properties of the antennas ...

In this thesis, the nonlinear optical properties as well as the ultrafast temporal dynamics of hybrid plasmonic systems are studied. The model system under investigation simultaneously provides localized plasmonic modes in a metallic nanowire grating and photonic modes in an adjacent dielectric waveguide slab. The coupling of the modes leads to the formation of polaritonic eigenstates and signi...

Nonlinear optical nanocrystals have been recently introduced as a promising alternative to fluorescent probes for multiphoton microscopy. We present for the first time a complete survey of the properties of five nanomaterials (KNbO(3), LiNbO(3), BaTiO(3), KTP, and ZnO), describing their preparation and stabilization and providing quantitative estimations of their nonlinear optical response. In ...
