Semiconductor Ring Lasers Coupled by a Single Waveguide
W. Coomans, L. Gelens, G. Van der Sande +4
We experimentally and theoretically study the characteristics of semiconductor ring lasers bidirectionally coupled by a single bus waveguide. This configuration has, e.g., been sug…
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…
Excitability in semiconductor microring lasers: Experimental and theoretical pulse characterization
L. Gelens, L. Mashal, S. Beri +4
We characterize the operation of semiconductor microring lasers in an excitable regime. Our experiments reveal a statistical distribution of the characteristics of noise-triggered…
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…
