    • Cryptography in coherent optical information networks using dissipative metamaterial gates 

      Xomalis, Angelos; Demirtzioglou, Iosif; Jung, Yongmin; Plum, Eric; Lacava, Cosimo; Petropoulos, Periklis; Richardson, David J.; Zheludev, Nikolay I. (2019)
      All-optical encryption of information in fibre telecommunication networks offers lower complexity and far higher data rates than electronic encryption can deliver. However, existing optical layer encryption methods, which ...
    • Fibre-optic metadevice for all-optical signal modulation based on coherent absorption 

      Xomalis, Angelos; Demirtzioglou, Iosif; Plum, Eric; Jung, Yongmin; Nalla, Venkatram; Lacava, Cosimo; MacDonald, Kevin F; Petropoulos, Periklis; Richardson, David J; Zheludev, Nikolay I (2018)
      Recently, coherent control of the optical response of thin films in standing waves has attracted considerable attention, ranging from applications in excitation-selective spectroscopy and nonlinear optics to all-optical ...
    • Picosecond all-optical switching and dark pulse generation in a fibre-optic network using a plasmonic metamaterial absorber 

      Xomalis, Angelos; Demirtzioglou, Iosif; Jung, Yongmin; Plum, Eric; Lacava, Cosimo; Petropoulos, Periklis; Richardson, David J.; Zheludev, Nikolay I. (2018)
      Coherent interaction of two light waves on a film of subwavelength thickness provides remarkable opportunities for controlling intensity and polarization of light beams as well as all-optical image processing. Here, we ...
