Abstract


In this work, we use the generalized nonlinear Schrödinger 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.
