| 摘 要： | 阐明了在研究半导体光放大器对光脉冲放大这一动态过程中通常采用常数载流子寿命近似这一处理方法是不理的。通过考虑放大器中载流子的实际复合机制，数值模拟了脉冲数据流通过放大器后脉冲的时域分布，并与采用常数载流子寿命近似所得的结果进行了比较。结果表明，二者具有明显的差异。 |

| Abstract: | The paper describes that the processing method using constant carrier lifetime approximation in investigating the dynamic process of amplifying light pulse with semiconductor light amplifier is unreasonable. Through considering the practical composite mechanism of carrier in amplifier, the time domain distribution of the pulse after the pulse data stream passing through the amplifier is simulated by a numerical method and is compared with the results obtained with constant carrier lifetime approximation. The results show that these two have an obvious difference. |
