摘　　要：文章采用拟解法求出了含有TOD、非线性色散、自陡峭、SFS的复Ginzburg-Lardau精确的暗类孤子解,并给出了解存在的条件;又采用数值实验方法结合理论分析证明了暗孤子的稳定性.从而得出了用飞秒级暗孤子作为光通信传播的载体比特率高、稳定性高的结论.We present an exact analytical dark solitonlike solution of Ginzburg-Landau and the requirement of exist dark soliton solution for a fs laser pulse,including TOD, nonlinear dispersion,and SFS by employing ansatz solution, and a typical example is analyzed. The stability of the solution is investigated numerically and theoretically.
