摘要

我们介绍了一个通用的、易于实现的高斯过程模型，该模型为光纤芯半径波动的建模提供了一个灵活的框架。该模型的灵活性允许易于修改的纤维轮廓，以适应已知的特性，如强迫轮廓通过仔细测量半径在特定点。然后用该模型说明了波动对宽跨度四波混频系统效率的巨大影响。此外，通过优化简单阶跃折射率光纤的光纤设计，我们表明，即使在存在较大芯半径波动的情况下，四波混频的效率也可以大大提高。

Enhancing four-wave mixing efficiency in optical fibers: the role of core radius fluctuations and mitigation strategies.

We introduce a versatile, easy-to-implement Gaussian process model that provides a flexible framework for modeling core-radius fluctuations of an optical fiber. The flexibility of the model allows for easy modification of the fiber profile to fit known characteristics, such as forcing the profile through carefully measured radii at specific points. The model is then used to show the drastic impact that fluctuations have on the efficiency of wide-spanning four-wave mixing systems. Furthermore, by optimizing the fiber design of a simple step-index fiber, we show that the efficiency of the four-wave mixing can be drastically improved even in the presence of large core-radius fluctuations.
