| 摘 要： | 理论分析了拉曼光纤放大谱与多波长泵浦光功率和波长的关系.考虑到泵浦光与泵浦光,泵浦光与信号光的拉曼相互作用,得出一个增益数组,增益数组就是离散的宽带拉曼光纤放大增益谱.对任何形态的宽带拉曼光纤放大增益谱,可以设定对应的增益数组,把泵浦光功率和波长组成二维坐标系,遍取坐标系中的各点,求出各组点对应的增益数组,找出最接近设定的增益数组,这组泵浦光功率及波长就是最优的解决方案.

| Abstract: | The relation between the possible gain profiles with multiple pumps in Raman amplifiers is studied. A gain array is exported when the pump-to-signal and pump-to-pump Raman scattering are taken into account. The gain array is a discrete gain profile, whatever Raman gain profiles are, the gain array is acquired correspondingly. On the other hand, the power and wavelength of pumps can form a coordinate 2-dimensionally, the range of which is so limited that the coordinate must be chosen as many as possible until the gain array is found. The group of coordinate is the optimization of multiple pumps. |
