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…
