    • Low-frequency fluctuations in external cavity semiconductor lasers: understanding based on a simple dynamical model 

      Prasad, Awadhesh; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (Institute of Physics, 2001-08)
      We investigate the dynamical origin of low-frequency fluctuations (LFFs) in external cavity semiconductor lasers by utilizing a simplified, three-dimensional model derived from the infinite-dimensional Lang-Kobayashi (LK) ...

    • Self-organization of coupled nonlinear oscillators 

      Gavrielides, Athanasios; Kottos, Tsampikos; Kovanis, Vassilios; Tsironis, George (EDP Sciences, 1998-12-01)
      The effects of impurities introduced into a lattice of strongly coupled oscillators are studied. Contrary to our expectations, a single impurity can control the chaotic behavior of a long array of chaotic oscillators and ...
