“…However, this particular VA-based approach cannot capture the characteristic breathing behavior of the DM soliton. To produce these dynamical features, one may follow the VA approach adopted in [51]. Alternatively, VA-predicted equations (4) and (5) can be solved in conjugation with a suitable numerical method, for the analysis of the formation of stable solitons.…”

“…Another issue arises due to the ultrashort duration and high peak power of the output of the fiber laser. The high power may excite fifth-order nonlinear effects [49][50][51][52]. Although the quintic nonlinear term is weak in comparison with the basic cubic nonlinearity, the combined action of the self-focusing cubic and defocusing nonlinearities, which correspond, respectively, to real parts of the cubic and quintic susceptibilities, χ 3 and χ 5 , gives rise to noteworthy pulse features and dynamics.…”

We address the generation and interaction of dispersion-managed dissipative solitons (DMDSs) in a model of fiber lasers with the cubic-quintic nonlinearity, multiphoton absorption and gain dispersion. Both anomalous and normal segments of the dispersion map include random dispersion fluctuations. Effects of the gain dispersion, higher-order nonlinearity and randomness on the generation of DMDS are demonstrated. The solitons exhibit breather-like evolution, and are found to be robust, up to a certain critical level of the random-dispersion component, which is sufficiently high. The roles of multiphoton absorption, gain dispersion and nonlinearity on the DMDS are also identified in the absence of randomness. Pair wise interactions of solitons lead, most typically, to their merger, with breaking of the left-right symmetry. The outcome of the collisions is more sensitive to the initial temporal separation between the solitons than to their phase difference.

Fiber optics telecommunication is the currently established backbone infrastructure for most of the information flow across the world. New services and applications are causing an exponential increase in Internet traffic, increasing transmission rate, and high bandwidth-demanding applications have been propelling the data rate per wavelength to approach the speed limit of electronics. In a few years, the current fiber optic communication system infrastructure will not be able to meet this demand because fiber nonlinearity dramatically limits the information transmission rate. Also, the dispersion phenomenon is a problem for high bit rates and long-haul optical communication systems. An easy solution to this problem is optical solitons pulses that preserve their shape over long distances. An optical soliton is formed by balancing nonlinearity (self-phase modulation) and dispersion phenomenon (group velocity dispersion). In this review article, a detailed study of optical solitons is presented along with its recent progress. Advanced numerical methods such as Darboux transform (DT), digital back propagation, split step Fourier, and forward–backward methods are also discussed in this paper which is used for solving higher-order solitons.
