Effects of nonlinear absorption and third order dispersion on soliton propagation in optical fiber
In this work, we use the generalized nonlinear Schrodinger equation to study propagation of ultrashort optical pulses in the presence of self-phase modulation, nonlinear absorption and third-order dispersion. The combined effect of the third-order dispersion and nonlinear absorption on amplitude, center location and phase of the soliton has investigated by approximate analytical method.
