“…The system seemingly has four amplitude attractors; therefore, the hopping between them (with appropriate frequency and level of background noise) can lead to surpassing of RW threshold. This situation apparently was similar to the situation that observed during pump modulation [8]. Probably, this happens because of the intrinsic low-frequency modulation of a signal power (see Fig.…”

A fiber mode-lock laser allows generation of the optical rogue wave (ORW) at different time scales. The criteria for distinguishing between them is a comparison of the event lifetime with the main characteristic time of the system. The characteristic time can be estimated from the decay of an autocorrelation function (AF).Thus, in comparison with AF characteristic time, fast optical rogue wave (FORW) events have duration less than the AF decay time and it appeared due to pulse-pulse interaction and nonlinear pulses dynamics. While slow optical rogue wave (SORW) have a duration much more longer than the decay time of the AF which it papered due to hopping between different attractors. Switching between regimes can be managed by change the artificial birefringence that induced in a laser cavity. For understanding the role playing by the periodical amplification and the resonator, we have performed an unidirectional fiber laser experiments without a saturable absorber. This laser experiment allowed to generate of most of the RW patterns which were either observed experimentally or predicted theoretically. In this way, we have observed the generation of an FORW along with SORW under similar conditions. Most of the patterns were found to be mutually exclusive which means that only one RW mechanism was realized in each regime of generation. Keywords: rogue wave, fiber laser, slow rogue wave, fast rogue wave, rogue wave's interaction, rogue waves collision. INTRODUCTIONA rogue wave as a concept has been initially introduced in oceanography to describe rare events, colloquially called "freak" waves. These waves have amplitudes that were much larger than average ones that resulted in destructive impact in nature and society [1]. Investigation of mechanisms which cause appearing of rogue wave (RW) has practical importance due to the damage which they cause in real-world scenarios. Meanwhile, an intrinsic scarcity of events, as well as evident technical difficulties to perform full-scale experiments, are the main obstacles for understand and predict RWs. Mode-locked lasers are perfect candidates to be test-bed systems for investigating conditions for RWs' emergence and mitigation [2]. Lasers with a high repetition rate of pulses provide an opportunity to obtain a huge amount of data under laboratory-controlled conditions in relatively short time. Previously, in the context of mode-locked fiber lasers, the ORW mostly have been observed at regimes of chaotic bunches of noise-like pulses or soliton rain [3]. Also, it has been found that ORW can be generated in mode-locked lasers as a result of the interaction of dissipative solitons interacting through overlapping of their tails or by dispersive pulses [4]. An extensive study of the mechanisms of formation of ORWs have been done either experimentally or theoretically in fiber lasers with nonlinearly driven cavities [5], Raman fiber amplifiers and lasers [6] and fiber lasers via modulation of pump [7]. In the other hand, the hopping has also been investigated as a sour...

“…This makes this device very promising for many applications where smallamplitude external modulation is required to control the laser dynamics. The mathematical model and experimental arrangement of the EDFL used in this work have been developed by Pisarchik et al [6][7][8][9][10][11][12].…”

“…The EDFL with coherent radiation at the wavelength of 1560 nm is an excellent device for applications in medicine, remote sensing, reflectometry, and all-optical fiber communications networks [1,2]. Rare-doped fiber lasers subjected to external modulation from semiconductor pump lasers are known to exhibit chaotic dynamics [3][4][5][6][7][8][9][10][11][12]. Besides, a very important advantage of the EDFL working in a chaotic regimen is its application to the development of basic logic gates [13], since it can process different logical gates and implements diverse arithmetic operations.…”

In this chapter, we present the experimental and numerical study of an optoelectronics flexible logic gate using a chaotic erbium-doped fiber laser. The implementation consists of three elements: a chaotic erbium-doped fiber laser, a threshold controller, and the logic gate output. The output signal of the fiber laser is sent to the logic gate input as the threshold controller. Then, the threshold controller output signal is sent to the input of the logic gate and fed back to the fiber laser to control its dynamics. The logic gate output consists of a difference amplifier, which compares the signals sent by the threshold controller and the fiber laser, resulting in the logic output, which depends on an accessible parameter of the threshold controller. The dynamic logic gate using the fiber laser exhibits high ability in changing the logic gate type by modifying the threshold control parameter.

“…48 A crucial concept used to quantify the time that it takes on average to leave a particular stable state is the mean first passage time or Kramer's law. [49][50][51] Noise-induced critical transitions appear, e.g., in laser systems, 52 in neuron populations, 53 or in the climate system. 54 Different aspects, which are related to such noise-induced dynamics in multistable systems, are outlined in Refs.…”

Multistability refers to the coexistence of different stable states in nonlinear dynamical systems. This phenomenon has been observed in laboratory experiments and in nature. In this introduction, we briefly introduce the classes of dynamical systems in which this phenomenon has been found and discuss the extension to new system classes. Furthermore, we introduce the concept of critical transitions and discuss approaches to distinguish them according to their characteristics. Finally, we present some specific applications in physics, neuroscience, biology, ecology, and climate science.
