Solitary and Coupled Semiconductor Ring Lasers as Optical Spiking Neurons
Werner Coomans, Lendert Gelens, Stefano Beri +2
We theoretically investigate the possibility of generating pulses in an excitable (asymmetric) semiconductor ring laser (SRL) using optical trigger pulses. We show that the phase d…
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…
Optical injection in semiconductor ring lasers
W. Coomans, S. Beri, G. Van der Sande +2
We theoretically investigate optical injection in semiconductor ring lasers and disclose several dynamical regimes. Through numerical simulations and bifurcation continuation, two…
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…
A phase-space approach to directional switching in semiconductor ring lasers
L. Gelens, G. Van der Sande, S. Beri +1
We show that a topological investigation of the phase space of a Semiconductor Ring Laser can be used to devise switching schemes which are alternative to optical pulse injection o…
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…
