【摘要】 以掺铒光纤放大器（ＥＤＦＡ）的均匀展宽两能级模型为基础，提出一种直接求解掺铒光纤中的粒子数反转度分布以数值模拟ＥＤＦＡ的新方法。其优点是准确、高效、通用于各种复杂结构的ＥＤＦＡ和任意模型参数设置，掺铒光纤的背景损耗或者激发态吸收也能考虑在内。在精确测量掺铒光纤参数的基础上将模拟和实验结果作了对比分析并得到合理的一致。更多还原

【Abstract】 In this paper, a new method is proposed for the numerical simulation of erbium doped fiber amplifiers (EDFA′s), which are modeled as homogeneously broadened two level systems. The basic point of the method is to first solve out the population inversion along the erbium doped fiber, then calculate other amplifier properties. This approach is highly efficient and accurate for the simulation of various complex structure EDFA′s with arbitrary setup of modeling parameters. Fiber background loss or excited state absorption can also be considered. Based on the accurate measurement of fiber parameters, a comparison between the experimental and simulated results shows reasonable agreement.更多还原
