“…The stability analysis of the different solitons as solutions of the GNLSE, that is, of the PDE, remains a considerable challenge. Finally, recent experiments [33] have shown the feasibilities of creating waveguides with higher even order dispersions, such as sextic (β 6 ), octic (β 8 ), and decic (β 10 ) dispersions. Our analysis constitutes the first step towards understanding the existence of solitons for different configuration of such higher-order dispersion terms.…”

“…Thus, across the bandwidth of the signal-pulse, the dispersion profile is ideally symmetric about the central wavelength-e.g., for ultrashort <100 fs pulses, the dispersion profile should be symmetric across a bandwidth range less than 50 nm. There are a plethora of waveguides that satisfy this symmetry requirement from dispersion engineered photonic crystal fibers to the system described in [35]. Furthermore, we find from full numerical simulations that the symmetry condition is not strictly necessary (see Section 3 for related discussion) and introduces little error for moderate odd-order dispersion coefficients (taken about the central wavelength of the signal) if Equation ( 4) is modified to Equation ( 5), given as follows:…”

“…Following the experimental observation of bright solitons supported by fourth-order dispersion [1], the theory of bright solitons with pure-quartic dispersion [2], mixed second-and fourth-order dispersion [3] and pure dispersion of higher even orders [4] has become well established. The experimental work was enabled by the development of a fiber laser with conveniently programmable dispersion [4,5]. All of these bright solitons exist when the highest-order of dispersion is negative.…”

“…The effect of dominant higher-order normal dispersion was considered in the φ 4 Klein-Gordon model, in both the pure quartic form [19,20] and in the presence of both quadratic and quartic terms [21]. These results for real fields point to intricate soliton interactions.…”
