摘要:

自发拉曼散射(SpRS)是一种弱非线性效应,尤其在经典-量子共存传输和传感应用中具有重要性。在经典传输中,相关的拉曼效应是受激拉曼散射(SRS),最近的研究已探讨了其在空间分组多模(SDM)光纤中的表现。SpRS与SRS之间存在内在联系,使先前的SRS结果能够为SpRS模型提供信息。在本工作中,我们将针对单模光纤(SMF)推导出的SpRS模型扩展至具有多个退化模式组的SDM光纤,涵盖斯托克斯和反斯托克斯带。所提出的模型是一种有用的、与光纤设计无关的工具,用于评估光链路中的散射噪声,并通过在实际部署的多芯光纤(MCF)和多模光纤(MMF)中的实验测量加以验证,显示出良好的一致性。

英文摘要:

Spontaneous Raman scattering (SpRS) is a weak non-linear effect, particularly relevant to classical-quantum coexistence transmission and sensing applications. In classical transmission, the relevant Raman effect is stimulated Raman scattering (SRS), and recent studies have examined it in space-division multiplexing (SDM) fibers. An intrinsic relation between SpRS and SRS allows previous SRS results to inform SpRS models. In this work, we extend SpRS models derived for single-mode fibers (SMFs) to SDM fibers with multiple mode groups of degenerate modes, covering both Stokes and anti-Stokes bands. The proposed model is a useful, fiber-design-independent tool for evaluating scattered noise in optical links, and it is validated through experimental measurements in field-deployed multi-core fibers (MCFs) and multi-mode fiber (MMF), showing good agreement.
