Plasmonic metaplatforms for enhanced light control

Abstract

In this talk I will discuss our work on the way light confinement within plasmonic nanostructures leads to new regimes of light manipulation and control. Firstly, I will discuss the way dispersion engineering may lead to new regimes for controlling nonlinear light-material interaction, including phase mismatch-free and broadband operation. I will discuss generation of classical and quantum light in such systems. Secondly, I will highlight our theoretical works on the study of magnetized nanoplasmonic structures. Specifically, as I will demonstrate magnetization combined with the symmetry breaking naturally available in plamonic systems leads to topologically nontrivial regimes of light propagation, which is manifested in one-way propagating and rotating modes. Lastly, I will discuss our experimental work on light absorption within ultrathin film metallic nanostructures and potential applications for optoelectronics.
