The tunability of the DP is demonstrated in graphene-based photonic superlattices by adjusting the graphene permittivity via the optical Kerr effect or electrical doping. The robustness of DPs is demonstrated in plasmonic lattices by showing that even very high levels of disorder are unable to localize the modes located near the DP. The robustness of the DP also manifests itself in the fact that the inversely-proportional dependence of the transmission on the lattice length near the DP remains unchanged under strong disorder. date: 2016-09 date_type: published official_url: http://dx.doi.org/10.1109/JSTQE.2016.2521711 oa_status: green full_text_type: other language: dut primo: open primo_central: open_green verified: verified_manual elements_id: 1064500 doi: 10.1109/JSTQE.2016.2521711 lyricists_name: Panoiu, Nicolae-Coriolan lyricists_id: NPANO59 full_text_status: public publication: IEEE Journal on Selected Topics in Quantum Electronics volume: 22 number: 5 article_number: 5000509 issn: 1077-260X citation: Deng, H; Chen, X; Malomed, BA; Panoiu, NC; Ye, F; (2016) Tunability and Robustness of Dirac Points of Photonic Nanostructures.
