Excitability in optical systems close to Z2-symmetry
Stefano Beri, Lilia Mashall, Lendert Gelens +5
We report theoretically and experimentally on excitability in semiconductor ring lasers in order to reveal a mechanism of excitability, general for systems close to Z2-symmetry. Th…
Topological insight into the non-Arrhenius mode hopping of semiconductor ring lasers
S. Beri, L. Gelens, M. Mestre +6
We investigate both theoretically and experimentally the stochastic switching between two counter-propagating lasing modes of a semiconductor ring laser. Experimentally, the reside…
Exploring multi-stability in semiconductor ring lasers: theory and experiment
L. Gelens, S. Beri, G. Van der Sande +4
We report the first experimental observation of multi-stable states in a single-longitudinal mode semiconductor ring laser. We show how the operation of the device can be steered t…
Design issues of a variable thermal resistance
V. Szekely, G. Mezosi
Some years ago we have proposed a thermal mount with electronically variable thermal resistance [1]. In this earlier work the feasibility of such a structure has been demonstrated.…
