Hybrid architectures: enabling 4-dimensional plasmonic-photonic crystals

In order to realize the regime of strong coupling between Bloch modes of periodically structured dielectric and surface plasmon polariton modes of corrugated metal film we prepared 2-dimensional slab hybrid plasmonicphotonic crystals. Angle-resolved transmission/reflectance spectroscopy was used to assess the composition of guided modes in such hybrid crystals. In the case of a monolayer photonic crystal encapsulated in a plasmonic waveguide we achieved the splitting of major resonances, which was interpreted in terms of mode hybridization and controlling the spatial localization of modes.
