1. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures
Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

2. Exciton-plasmon interactions in metal-semiconductor nanostructures
Abstract : Semiconductor quantum dots and metal nanoparticles feature very strong light-matter interactions, which has led to their use in many photonic applications such as photodetectors, biosensors, components for telecommunications etc.Under illumination both structures exhibit collective electron-photon resonances, described in the frameworks of quasiparticles as exciton-polaritons for semiconductors and surface plasmon-polaritons for metals.

3. Nanoplasmonic Structures for Bio/Chemo Sensing
Abstract : Localized surface plasmon resonances (LSPR's) in noblemetal nanostructures are sensitive to refractive index changes close to the metal surface, and the LSPR's can therefore be utilized to sense molecular binding reactions. This thesis focuses on fundamental properties and proof-of-principle sensing studies of nanoplasmonic structures relevant for molecular detection. READ MORE

4. Optical properties of active photonic materials
Abstract : Because of the generation of polaritons, which are quasiparticles possessing the characteristics of both photonics and electronics, active photonic materials offer a possible solution to transfer electromagnetic energy below the diffraction limit and further increase the density of photonic integrated circuits. A theoretical investigation of these exciting materials is, therefore, very important for practical applications. READ MORE

5. Near-Field Radiative Heat Transfer between Plasmonic Nanostructures
Abstract : Radiative heat transfer (RHT) due to coupled electromagnetic near field scan significantly exceed that dictated by Planck’s law. Understanding such phenomenon is not only of fundamental scientific interest, but also relevant to a broad range of applications especially connected to nanotechnologies. READ MORE
