Journal ArticleDOI
Deterministic Optical Rogue Waves
Cristian Bonatto,Michael Feyereisen,Stephane Barland,Massimo Giudici,Cristina Masoller,José R. Rios Leite,José R. Rios Leite,Jorge R. Tredicce,Jorge R. Tredicce +8 more
TL;DR: Simulations of a simple rate equation model show good qualitative agreement with the experiments and provide a framework for understanding the observed extreme amplitude events as the result of a deterministic nonlinear process.
Journal ArticleDOI
Periodicity hub and nested spirals in the phase diagram of a simple resistive circuit.
TL;DR: Familiar period-adding current and voltage cascades are shown to be just restricted one-parameter slices of an exceptionally intricate and very regular onionlike parameter surface centered at the focal hub which organizes all the dynamics.
Journal ArticleDOI
Self-similarities in the frequency-amplitude space of a loss-modulated CO2 laser.
TL;DR: This work shows the standard two-level continuous-time model of loss-modulated CO2 lasers to display the same regular network of self-similar stability islands and suggests that the two-parameter space of class B laser models and that of a certain class of discrete mappings could be isomorphic.
Journal ArticleDOI
Accumulation horizons and period adding in optically injected semiconductor lasers.
TL;DR: In this article, the hierarchical structuring of islands of stable periodic oscillations inside chaotic regions in phase diagrams of single-mode semiconductor lasers with optical injection was studied, and the authors showed that such structures may compromise applications operating with chaotic signals such as secure communications.
Journal ArticleDOI
Excitability in optically injected semiconductor lasers: Contrasting quantum- well- and quantum-dot-based devices
Bryan Kelleher,Bryan Kelleher,Cristian Bonatto,Cristian Bonatto,Guillaume Huyet,Guillaume Huyet,Stephen P. Hegarty +6 more
TL;DR: Experimental observations show the marked differences in the pulse shapes while theoretical considerations reveal the underlying mechanism responsible for the contrast, identifying the increased stability of quantum-dot lasers to perturbations as the root.
