Abstract
When a low-power finite-energy Airy pulse (FEAP) and a high-power soliton pulse simultaneously propagate in an optical fiber, we numerically study the evolution of the FEAP affected by higher-order effects, including third-order dispersion (TOD), Raman scattering and self-steepening (SS). It is found that shedding solitons are generated from the FEAP due to the effect of cross-phase modulation (XPM). The TOD only affects the center position of the shedding soliton, but does not change the spectrum structure. The truncation coefficient of a FEAP, TOD and SS can be used to manipulate the Raman-induced frequency shift (RIFS). It is demonstrated that the RIFS is suppressed obviously by both positive TOD, SS and a small truncation coefficient, but the RIFS is enhanced by the negative TOD and a larger truncation coefficient. Further, we comparatively study the simultaneous contributions of TOD, Raman, and SS to the evolution of a FEAP and a Sech pulse, respectively. It is shown that the FEAP generates some static solitons besides the conventional Raman soliton and the whole spectrum is broadened that extended towards to the blue-shifted side besides the conventional red-shifted components. Our results indicate that the FEAP has potential application in supercontinuum generation and broadband sources.
