We also show that the nonlinear response of our structure can be further tuned with a bias electric field, enabling the realization of electrically tunable nonlinear metamaterials.We acknowledge the support by the Australian Research Council, the Australian National Computational Infrastructure, and the ACT Node of Australian National Fabrication Facility.http://www.sherpa.ac.uk/romeo/issn/0003-6951..."Publishers version/PDF may be used on author's personal website, institutional website or institutional repository" from SHERPA/RoMEO site (as at 24/09/15).
