“…Ref. [4] infers that two pulses get repulsive between each other when we consider cross-phase modulation (XPM) effects in normal dispersion regime by assuming non-coherent interaction, verified by later experimental reports [21]. Similar mechanism holds true here and deduces that XPM effects make two pulses attractive to each other in anomalous dispersion regime, which is indeed what we obtain in our case.…”

“…For a complete overview, Table 1 lists the most relevant experimental observation of two-soliton molecules exhibiting abundant discrete values of phase difference and interpulse separation in diverse configurations of fibre lasers (different wavelengths, difference dispersion conditions, different mode-locking techniques, etc.). At higher pumping power level, soliton molecules consisting of three and more than three solitons as well as bound states of bound solitons have been reported in sorts of fibre lasers [21,27,[45][46][47][48]. Figure 14 shows two typical examples of such multisoliton complexes observed by Zhao et al [47].…”

“…Afanasjev et al and Akhmediev et al also investigated analytically and numerically the existence and stability of bound states with π, 0 and ±π/2 phase differences [13][14][15]. So far bound states have been studied by simulated and/or experimental methods in types of fibre laser cavities, i.e., in soliton [16,17], stretched-pulse [18], gain-guided [19] and self-similar [20] regimes, as well as dissipative soliton regime associating with large net-normal dispersion and spectral filtering [21]. A lot of experimental observations of bound solitons have been reported in fibre lasers mode-locked by nonlinear polarization evolution (NPE) [22][23][24], nonlinear amplifying loop mirror (NALM) [8,25] and some real saturable absorbers (e.g., semiconductor saturable absorber mirror (SESAM) [26], carbon nanotubes (CNT) [27][28][29], graphene [30,31], topological insulator [32], molybdenum disulphide (MoS 2 ) [33] and black phosphorus [34]).…”

Featured Application: High-capacity telecommunication, advanced time-resolved spectroscopy, self-organization and chaos in dissipative systems. Abstract:Benefiting from ultrafast temporal resolution, broadband spectral bandwidth, as well as high peak power, passively mode-locked fibre lasers have attracted growing interest and exhibited great potential from fundamental sciences to industrial and military applications. As a nonlinear system containing complex interactions from gain, loss, nonlinearity, dispersion, etc., ultrafast fibre lasers deliver not only conventional single soliton but also soliton bunching with different types. In analogy to molecules consisting of several atoms in chemistry, soliton molecules (in other words, bound solitons) in fibre lasers are of vital importance for in-depth understanding of the nonlinear interaction mechanism and further exploration for high-capacity fibre-optic communications. In this Review, we summarize the state-of-the-art advances on soliton molecules in ultrafast fibre lasers. A variety of soliton molecules with different numbers of soliton, phase-differences and pulse separations were experimentally observed owing to the flexibility of parameters such as mode-locking techniques and dispersion control. Numerical simulations clearly unravel how different nonlinear interactions contribute to formation of soliton molecules. Analysis of the stability and the underlying physical mechanisms of bound solitons bring important insights to this field. For a complete view of nonlinear optical phenomena in fibre lasers, other dissipative states such as vibrating soliton pairs, soliton rains, rogue waves and coexisting dissipative solitons are also discussed. With development of advanced real-time detection techniques, the internal motion of different pulsing states is anticipated to be characterized, rendering fibre lasers a versatile platform for nonlinear complex dynamics and various practical applications.

“…When multiple stationary states are closely spaced (in frequency), they form bound states of solitons [2][3][4]. These have been observed in a number of experiments [5][6][7][8][9][10][11][12]. Under particular conditions, energy scalable spectral broadening occurs, keeping the amplitude constant.…”

In the presence of noise in normal dispersion fiber mode-locked lasers, "dissipative resonance" disappears, which leads to instability of spectral broadening and makes the asymptotic accumulation of energy impossible. We experimentally generate dissipative soliton molecules-like spectral peaks and rogue waves in the frequency domain in a self-mode-locked fiber laser. Due to noise in the initial triangular-shaped mode locked wave, these molecules are arranged in the form of lobes on the longer wavelength side, thus forming three virtual groups of soliton molecules. Further dissipative accumulation of power in the mode-locked wave ultimately leads to the formation of a blue-shifted group of three rogue waves, due to the effective fusion of adjacent soliton molecules. This is the first report of an experimental observation of blue-shifted and three rogue waves in a single experiment. The results have far reaching implications for experimentation with soliton collisions, optical rogue waves, and understanding of hydrodynamics.Index Terms-Passive mode-lock fiber lasers, normal dispersion, instability of dissipative soliton resonance, bound solitons, supercontinuum, rogue waves.

“…In the case of pulse attraction, the regime of bound solitons can occur. Bound steady states of two solitons were investigated in [14][15][16][17][18][19][20][21][22][23]. Steady states of such a two-soliton molecule with constant phase differences for the peak amplitudes of the solitons equal to π, π/2, and 0 were predicted.…”
