N2 - In this paper, we simulate the propagation of femtosecond pulses in one-pump fiber optical parametric amplifiers (1-P FOPAs). The coupled nonlinear Schrödinger equations (NLSEs) are solved using Runge-Kutta and Crank-Nicolson method and the impact of pump power, fiber loss, second- and third-order dispersion coefficients on pulse evolution along the fiber is investigated. The results show that including the dispersion and nonlinear effects changes the shape of the pump, signal and idler as they propagate along the fiber. M3 ER -
