摘要
为了准确预测反射型半导体光放大器(RSOA)中的放大自发辐射(ASE)噪声和掌握RSOA的最佳工作区间,在SOA宽带稳态模型以及高效动态模型的基础上,修改了RSOA的部分结构并将多阶迭代的算法运用到RSOA理论建模以及增益噪声指数测试中。实验结果表明RSOA在偏置电流大于130 mA时增益稳定在26 dB以上,噪声指数稳定在11 dB。且在偏置电流不变时,低输入功率-30 dBm时,RSOA处于最佳工作区间。该种新型RSOA模型满足且优于实际应用中RSOA的各项工作参数,测试结果对RSOA的产品优化设计和光网络单元最佳工作区间具有指导和改进的意义。
In order to accurately calculate ASE noise in RSOA and find the best working range of RSOA.First,based on the SOA broadband steady-state model and efficient dynamic model,the part of structures of RSOA was modified.Second,the multi-order iterative algorithm was applied to RSOA theoretical modeling and gain noise figure test.when the bias current was more than 130 mA,the gain was stable at 26 dB and the noise figure was stable at 11 dB.At a constant bias current and a low input power of-30 dbm,RSOA is in the best working condition.the test results satisfy and are superior to the working parameters of RSOA in practical application.The test results have a great role in guiding and improving performance for the superior design of RSOA products and the optimal working interval of optical network units.
