    • Broadband chaos generated by an optoelectronic oscillator. 

      Callan, KE; Gao, Z; Gauthier, Daniel J; Illing, L; Schöll, E (Phys Rev Lett, 2010-03-19)
      We study an optoelectronic time-delay oscillator that displays high-speed chaotic behavior with a flat, broad power spectrum. The chaotic state coexists with a linearly stable fixed point, which, when subjected ...
    • Pulse-train solutions and excitability in an optoelectronic oscillator 

      Callan, KE; Gauthier, Daniel J; Rosin, DP; Schöll, E (EPL, 2011-11-01)
      We study an optoelectronic time-delay oscillator with bandpass filtering for different values of the filter bandwidth. Our experiments show novel pulse-train solutions with pulse widths that can be controlled over ...
