Frequency comb generation through the locking of domain walls in doubly resonant dispersive optical parametric oscillators
P. Parra-Rivas, L. Gelens, T. Hansson +2
In this letter we theoretically investigate the formation of localized temporal dissipative structures, and their corresponding frequency combs in doubly resonant dispersive optica…
Quadratic Soliton Combs in Doubly-Resonant Second-Harmonic Generation
T. Hansson, P. Parra-Rivas, M. Bernard +3
We report a theoretical investigation of quadratic frequency combs in a dispersive second-harmonic generation cavity system. We identify different dynamical regimes and demonstrate…
Third-order chromatic dispersion stabilizes Kerr frequency combs
Pedro Parra-Rivas, Damia Gomila, Francois Leo +2
Using numerical simulations of an extended Lugiato-Lefever equation, we analyze the stability and nonlinear dynamics of Kerr frequency combs generated in microresonators and fiber…
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…
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…
