“…Where and Г are the material properties of the laser, the linewidth enhancement factor, the laser frequency (detuning), and the real and imaginary part of the complex electric field respectively, the normalized population inversion, γ the injected field strength. Considering the effect of an optical perturbation [1] due to the presence during a certain time interval of light ray in the beam path from the pump laser (master) to the injected laser (slave), the mathematical model of the semiconductor laser subject to periodic optical perturbation is given as:…”

“…Wieczorek et al, 2005 [17] discovered a new dynamical effect (multipulse excitability) and some phenomena including cascades of bifurcation, multistability and sudden chaotic transitions in an optically injected semiconductor laser. Recently, Torre et al, 2019 [1] explored the combined effect of excitability and extreme pulse emission for the detection of variation in the strength of the injected field of semiconductor laser. It is important to note that these different investigations have been carry out on the dynamics of semiconductor lasers because of their potential applications in engineering and particularly in injection locking [18] frequency stabilization [19] linewidth narrowing and chirp reduction [20].…”

It is well known that during a certain interval of time, a molecule of gas in the beam path from the pump laser (master) to the injected laser (slave) can decrease the power injected [1]. In this contribution, we consider a well-known rate equation model of semiconductor laser to explore numerically the effect of a periodic perturbation from the pump laser (master) on the dynamical behavior of the injected laser (slave). Using nonlinear diagnostic tools such bifurcation diagrams, graph of maximum Lyapunov exponent, phase portraits, Poincare sections, basin of attraction and two parameter diagrams, the dynamical behavior of the model is analyzed in terms of its parameters. The coexistence of periodic and chaotic attractors as well as the occurrence of ten different attractors (symmetric and asymmetric) and transient chaos are demonstrated. Finally, PSpice simulations are performed to support numerical results.

“…Here we apply this methodology to a well-known laser system that can display locked behaviour: an optically injected semiconductor laser. Under constant injection conditions the laser displays different dynamical regimes, including the socalled injection-locking (where the laser emits a constant output whose wavelength is identical to that of the injected light), periodic oscillations, and chaotic oscillations [6][7][8][9][10][11][12][13] , with or without extreme fluctuations [14][15][16] . When the phase of the injected field is perturbed, under appropriate conditions the laser emits pulses that are locked to the phase perturbations, and whose excitable nature was demonstrated in 17,18 .…”

We use statistical tools to characterize the response of an excitable system to periodic perturbations. The system is an optically injected semiconductor laser under pulsed perturbations of the phase of the injected field. We characterize the laser response by counting the number of pulses emitted by the laser, within a time interval, ∆T , that starts when a perturbation is applied. The success rate, SR(∆T ), is then defined as the number of pulses emitted in the interval ∆T , relative to the number of perturbations. The analysis of the variation of SR with ∆T allows to separate a constant lag of technical origin and a frequency-dependent lag of physical and dynamical origin. Once the lag is accounted for, the success rate clearly captures locked and unlocked regimes and the transitions between them. We anticipate that the success rate will be a practical tool for analyzing the output of periodically forced systems, particularly when very regular oscillations need to be generated via small periodic perturbations.
