Abstract

In this paper, using the Lagrangian approach, we study the modulational instability of the one-dimensional optical solitons with a nonlinear Schrödinger equation in pure quartic media along with competing cubic and quintic nonlinearities. By adding weak perturbation to the plane wave solution, we deduced the dispersion relation which accommodates the impacts of fourth-order dispersion strength, cubic and quintic nonlinearities. Following that, by employing a time-dependent variational approach, we find the stable and unstable regions of the optical solitons by tuning the fourth-order dispersion for competing cubic and quintic nonlinear strengths. We have also been able to identify the region of modulational instability growth rate. We complemented our analytical results with full numerical simulations and good agreement has been found.
