| 摘 要： | 本采用计算机系统仿真的方法，研究了应用相敏光放大器(PSA)作为在线放大器的采用平均孤子传输方案的光孤子通信系统中，泵浦光与信号光之间的相位漂移、光纤色散对光孤子通信系统传输性能的影响。仿真的结果表明：泵浦光与信号光之间的相位漂移将导致孤子幅度的下降；由于PSA增益的相敏特性，光纤色散导致孤子脉冲主瓣幅度下降，脉宽展宽，出现旁瓣。 |

| Abstract: | In this paper, the effect of phase-shift between pumping and signal light and optical fiber dispersion parameter on the performance of average-soliton transmission system using PSA as in-line amplifiers has been analyzed theoretically by computer simulation.Our simulation results show that phase-shifting between pumping and signal light in PSA results in descending of soliton pulse amplitude and its width broadening. Because of the phase-sensitive nature of PSA's gain, fiber dispersion will also cause soliton pulse amplitude descending and its width broadening. |
| Keywords: | optical soliton transmission phase-sensitive amplifier average-soliton phase-shifting optical fiber dispersion computer simulation |
