摘要
介绍了一种改进的宽带分布式多泵浦喇曼放大器(DMRA)优化设计方法.通过研究多波长后向泵浦的喇曼放大器传输方程,采用合理的近似得出了快速DMRA的一个简化理论分析模型.通过对模拟退火算法几个优化环节的改进,使其能够更快速地应用于DMRA的多峰值问题的优化设计.利用该方法重点对C+L波段约80 nm带宽范围的DMRA进行了优化,在80 km传输光纤上,设计实现了开关增益10 dB,相对平坦度小于0.12,增益起伏小于1 dB的DMRA.与其他的DMRA设计方法相比,该方法使用较少的泵浦数目就能获得同样的增益带宽及平坦的谱特性.
Abstract
An improved Simulated Annealing(ISA) method for fast optimizing distributed multi-pump Raman amplifier(DMRA) was presented.A simple algorithm for counter-pumped DMRA was derived through reasonable approximations.The proposed ISA can effectively solve the multimodal optimization including the global and local optima in the DMRA.Optimization results show that,under the conditions of the ON-OFF gain of 10 dB,the relative gain flatness of <0.12 and the fiber haul of 80 km,amplifier bandwidths at larger 80 nm have been achieved with 4,5 and 6 pumps by using the optimization of the ISA.Comparing with other existing methods,the ISA method can attain a required low gain ripples and larger bandwidth with less pumps.
