Plasmonic and Metamaterial @ LiCryl


The group conducts research in the field of innovative, nanostructured materials. On such a scale, light-matter interaction can be tailored in order to reach the desired customization level. In particular, the optical properties of 1D, 2D and 3D nano-resonators are specifically engineered with the aim of experimenting completely new properties and phenomena. As mono-dimensional nanoresonators, the group has an expertise in a new kind of plasmonic crystals, denominated Hyperbolic Metamaterials, whose extreme anisotropy can be designed in order to achieve unprecedented phenomena among which supercollimation, perfect-lensing, extreme resolution bio-sensing, resonant gaining and thermal tunability are only few examples. Within the class of 2D nanoresonators, the group investigates the properties of a particular class of photonic meta-structures calld Photonic Quasi-Crystals (PQCs). Due to their specific arrangement, PQCs shows special optical features like extraordinary transmission. The thermal properties of metallic nano-spheres are investigated in order to engineer their thermo-plasmonic properties. With this aim, many particular arrangements of metallic nanoparticles are both experimentally and theoretically analysed from the single, monodispersed nano-particle, to the bottom-up assembled surfaces, also on stretchable substrates. In a wider scenario, the combination of tunable media with plasmonic subunits is considered to enable active functionalities of resulting devices (Active Plasmonics). In the end, the special optical features of plasmonic nano-shells are investigated. The interaction between gain media (e. g. fluorescent organic dyes) and all of these nanoresonating structures is investigated by means of Time Correlated Single Photon Counting experiments.
