The resonant interaction of light with nanostructures and metasurfaces enables the control of light properties beyond what is possible with bulk optical components. In this talk, I will discuss some results on random plasmonic metasurfaces for metal colouring , metasurfaces for nonlinear light structuring , and tunable hybrid nanostructures for optical phased arrays . I will also highlight the focus of my team on the high-performance computing tools to accelerate the simulation and design of such systems .
