Abstract

We propose a data-driven erbium-doped fiber amplifier (EDFA) gain model utilizing Gaussian process regression (GPR). An additive Laplacian and radial-basis function kernel is proposed for the GPR and was found to outperform deep neural network (DNN) methods while additionally providing prediction uncertainty. Performance is measured using mean absolute error (MAE) averaged across five different EDFAs with three manufacturers. The GPR achieves an MAE of 0.1 dB using 30 training samples in contrast to the DNN that achieves an MAE of 0.25 dB using 3000 training samples. Additionally, we demonstrate that active learning can be used to improve robustness and repeatability of convergence.

利用高斯过程回归进行数据驱动的掺铒光纤放大器增益建模

我们提出了一种利用高斯过程回归（GPR）的数据驱动型掺铒光纤放大器（EDFA）增益模型。我们为 GPR 提出了一种加性拉普拉斯和径向基函数核，发现其性能优于深度神经网络 (DNN) 方法，同时还提供了预测不确定性。性能采用平均绝对误差（MAE）进行测量，该平均绝对误差是由三家制造商生产的五种不同 EDFA 的平均值得出的。GPR 使用 30 个训练样本实现了 0.1 dB 的 MAE，而 DNN 使用 3000 个训练样本实现了 0.25 dB 的 MAE。此外，我们还证明了主动学习可用于提高收敛的稳健性和可重复性。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
