TL;DR: In this article, the authors present a modern approach to the theoretical and experimental study of complex nonlinear behavior of a semiconductor laser with optical injection-an example of a widely applied and technologically relevant forced nonlinear oscillator, and show that careful bifurcation analysis of a rate equation model yields a deeper understanding of already studied physical phenomena, and discovery of new dynamical effects, such as multipulse excitability.

TL;DR: This work presents an example of all three types of tipping in a simple global energy balance model of the climate system, illustrating the possibility of dangerous rates of change even in the absence of noise and of bifurcations in the underlying quasi-static system.

TL;DR: The dynamics and bifurcations of a single-mode semiconductor laser with optical injection, modeled by three-dimensional rate equations, are presented, to the best knowledge, yet, of the dynamics of injected semiconductor lasers.

TL;DR: In this article, a novel excitability type where a large excitable response appears when a system's parameter is varied gradually, or ramped, above some critical rate is studied, even though there is a unique stable quiescent state for any fixed setting of the ramped parameter.

TL;DR: An optically injected semiconductor laser can produce excitable multipulses that are organized by a generic codimension-two homoclinic bifurcation and should also be observable in other systems.
