Switchable and reconfigurable nanophotonics: from single antennas to complex systems
Résumé
I present results aimed at achieving nanoscale switchable and reconfigurable devices. A single nanoantenna can concentrate intensity and produce an enhanced excitation and readout of a nonlinear Kerr medium. Next to single-antenna building blocks, we look at highly multimode, complex environments where the light field is the result of interference of many possible light paths. New types of all-optical control are achieved through reconfiguring the light field and the medium itself, including ultrafast wave shaping and reciprocity effects.
