“…The fission of N -solitons in nonlinear optical fibers is naturally caused by higher-order linear and nonlinear effects [13], [14], [15], [16], such as the Raman-induced self-frequency shift [17], [18], self-steepening [19], and third-order dispersion (TOD), which are included into the corresponding generalized NLS equations [20], [21]. The point at which the fission occurs is, usually, the one where the bandwidth of the evolving N -soliton attains its maximum.…”

A mechanism for creating a Newton's cradle (NC) in nonlinear light wavetrains under the action of the third-order dispersion (TOD) is demonstrated. The formation of the NC structure plays an important role in the process of fission of higher-order (N -) solitons in optical fibers. After the splitting of the initial N -soliton into a nonuniform chain of fundamental quasi-solitons, the tallest one travels along the entire chain, through consecutive collisions with other solitons, and then escapes, while the remaining chain of pulses stays as a bound state, due to the radiation-mediated interaction between them. Increasing the initial soliton's order, N , leads to the transmission through, and release of additional solitons with enhanced power, along with the emission of radiation, which may demonstrate a broadband supercontinuum spectrum. The NC dynamical regime remains robust in the presence of extra perturbations, such as the Raman and self-steepening effects, and dispersions terms above the third order. It is demonstrated that essentially the same NC mechanism is induced by the TOD in finite segments of periodic wavetrains (in particular, soliton chains). A strong difference from the mechanical NC is that the TOD-driven pulse passing through the soliton array collects energy and momentum from other solitons. Thus, uniform and non-uniforms arrays of nonlinear wave pulses offer an essential extension of the mechanical NC, in which the quasi-particles, unlike mechanical beads, interact inelastically, exchanging energy and generating radiation. Nevertheless, the characteristic phenomenology of NC chains may be clearly identified in these nonlinear-wave settings too.

“…Resultantly, higher order solitons breakup into several fundamental solitons through the fission process. Such chaotic soliton fission process causes shot-to-shot noise in the supercontinuum spectrum [21,22]. However, in case of normal group velocity dispersion regime, for femtosecond intense pulses, SPM is the only mechanism behind the ultra wide spectral broadening [22].…”

2015): Design and analysis of equiangular spiral photonic crystal fiber for mid-infrared supercontinuum generation, Journal of Modern Optics, A design of equiangular spiral photonic crystal fiber (PCF) in As 2 Se 3 chalcogenide glass is reported for mid-infrared supercontinuum generation. Supercontinuum covering the 1.2-15 μm molecular fingerprint region is achieved using only 8 mm long designed PCF pumped with 50 fs laser pulses of 500 W peak power. The structural parameters have been tailored for all-normal dispersion characteristic. Proposed structure has high nonlinearity (γ = 12474 W −1 km −1 ) at 3.5 μm with very low and flat dispersion −2.9 [ps/(nm × km)]. Supercontinuum with such broadening and high coherence degree is applicable for mid-infrared spectroscopy, gas sensing, early cancer diagnostics and free space communication.
