  • Excitability in optical systems close to Z2-symmetry 
    Beri, S.; mashal, L.; Gelens, L.; Van der Sande, G.; Verschaffelt, G.; Danckaert, J. (North-Holland, 2010-01-18)
    We report theoretically and experimentally on excitability in semiconductor ring lasers in order to reveal a mechanism of excitability, general for systems close to Z 2-symmetry. The global shapes of the invariant manifolds ...
  • Square-wave oscillations in semiconductor ring lasers with delayed optical feedback 
    Mashal, L.; Van der Sande, G.; Danckaert, J.; Verschaffelt, G. (Opt. Express, 2012)
    We analyze experimentally and theoretically the effects of delayed optical cross-feedback in semiconductor ring lasers. We show that under appropriate conditions, feeding of only one directional mode back into the ...
