Abstract
The ability to actively manipulate optical signals at the nanoscale represents an essential tool in order to disclose the full potential of all-optical data processing. Complex optical networks can be competitive with electronic circuitry in terms of speed and dimensions, providing also lower power consumption. All-optical switching and modulation can be achieved exploiting optical nonlinearities in metals via ultrashort laser pulses. Plasmonic metamaterials represent an ideal platform to implement these functionalities, given their ability to support complex field distributions, which are geometry-controlled and impact the metamaterials ultrafast nonlinear response.
