Abstract

The dynamics of finite energy Airy pulse (FEAP) under the nonlinear Schrödinger equation with higher-order effects, including third-order dispersion (TOD), self-steepening (SS), and Raman scattering and in the presence of the linear potential is investigated. The linear potential that can control the trajectory of FEAP has been introduced as a unique technique to manipulate the frequency shift of FEAP. The results show that TOD and SS have a limited effect on the Raman-induced frequency shift, which decreases with the increase of the TOD and SS coefficients. The linear potential has no effect on the shape of the pulse and has a direct effect on the spectrum and leads to the frequency shift. The frequency shift is adjusted effectively with the linear potential, which can be obviously enhanced with the change of the linear potential strength.
