摘要
基于改进的耦合功率方程，提出了多芯光纤C + L频段SDM-WDM系统的信噪比计算模型。基于该模型，研究了MCF C + L波段WDM系统中芯间串扰（ICXT）和受激拉曼散射（SRS）对传输性能的影响。结果表明，SRS和ICXT都会对系统性能产生显著影响。此外，研究了四种优化通道入射功率的策略，以消除SRS的影响。结果表明，输出功率平坦化策略在系统容量和优化效率方面表现良好。
Transmission performance analysis and optimization of C+L band SDM-WDM system with weakly coupled multi-core fiber
Based on the improved coupled power equations, a signal-to-noise ratio (SNR) calculation model is proposed for multi-core fiber C + L band SDM-WDM systems. Based on this model, the effects of inter-core crosstalk (ICXT) and Stimulated Raman Scattering (SRS) on the transmission performance is investigated in the MCF C + L band WDM system. The results show that both SRS and ICXT will influence the system performance significantly. Furthermore, four strategies for optimizing the channel incident power are investigated for the SRS impact. The output power flattening strategy is found to perform well in terms of system capacity and optimization efficiency.
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
