Engineering light-matter interactions with photonic-plasmonic nanostructures: science and technology of sub-wavelength giant fields
"The control of materials, structures and electromagnetic fields on the nanoscale offers unprecedented opportunities to engineer linear and nonlinear optical processes for a variety of device applications. In particular, tailoring the distinctive plasmonic resonances of metal-dielectric nanostructures will enable highly specific, real-time, and multi-parametric detection of bio-chemical agents and bacteria pathogens on miniaturized optical chips. In this talk, I will give a panoramic overview of my research activities on the computational modelling, nanofabrication, and optical characterization of plasmonic chips for radiative rate engineering, colorimetric scattering and Raman sensing applications. Further, I will introduce multi-scale photonic-plasmonic media without translational invariance. These novel aperiodic systems, which are generated by deterministic rules, offer the greatest potential to achieve spatio-temporal energy localization and broadband enhancement of light-matter interactions for the creation and manipulation of intense (giant) sub-wavelength fields on optical chips."
