我们报告了掺锗渐变折射率多模光纤的设计、制造和实验表征，这些光纤是为实现模间布拉格散射四波混频过程的宽带操作而定制的。首先，我们表明增加核心直径会减少泵与信号/惰轮对之间的分离。其次，我们展示了转换效率带宽 (7 nm) 是之前使用一半光纤长度 (50 m) 实现的两倍多。 (C) 2018 年作者。
We report on the design, fabrication, and experimental characterization of germanium-doped graded-index multi-mode fibers that are tailored to achieve broadband operation for the inter-modal Bragg scattering four wave mixing process. First, we show that increasing the core diameter decreases the separation between the pumps and the signal/idler pair. Second, we demonstrate a conversion efficiency bandwidth (7 nm) of more than twice that achieved previously with half the fiber length (50 m). (C) 2018 Author(s).
