| 摘 要： | 双泵浦波在光纤中的传输可以用耦合非线性薛定谔方程来描述，在群速度失配不能忽略和可以忽略两种情况下进行增益计算，并采用升余弦滚降信号作为相位调制信号，从理论上得到了双泵浦光参量放大器增益的解析解与数值解，并由此得到增益曲线。得到采用不同波长的泵浦波，也就是在群速度失配的情况下，增益要比群速度匹配的情况下大些。采用不同波长的泵浦波有利于提高光参量放大器的增益。且在相位调制的上升和下降时间段，增益有起伏的特点。

| Abstract: | The two - pump wave transmission in optical fiber can be expressed by coupled nonlinear Schrodinger equation, and the gain of parametric amplifier can be computed at the condition of group velocity dismatching and matching. We adopt raised cosine shape as phase modulation signal, and get the analytical and numerical value of the gain and the gain curve. From these, we show that the gain is bigger in different pump wavelength, the same time, during rising and dropping time in the phase modulation, the gain is fluctuated. |
