Excitability in optical systems close to -symmetry

by Beri, S., Mashall, L., Gelens, L., Van der Sande, G., Mezosi, G., Sorel, M., Danckaert, J. and Verschaffelt, G.
Abstract:
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 of a saddle in the vicinity of a homoclinic loop determine the origin of excitability and the features of the excitable pulses. We show how to experimentally make a semiconductor ring laser excitable by breaking the Z 2 -symmetry in a controlled way. The experiments confirm the theoretical predictions.
