Abstract

We investigate reducing pump power requirements in super L-band erbium/ytterbium co-doped fiber amplifiers. We examine several pump configurations and find good trade-offs in performance and power when employing a hybrid pumping scheme that combines forward 915 nm cladding-pumping with backward 1480 nm core-pumping. Using experimental measurements with hybrid pumping, we train a neural network model to predict gain and noise figure. With the fast and precise neural network model, we examine the effect on performance (gain, noise figure and total electrical power consumption) as we vary the percentage of power dedicated to cladding vs. core pumping.

优化覆层泵浦 L 波段放大器电功率使用的混合泵浦技术

我们研究了如何降低超 L 波段铒/镱共掺光纤放大器对泵浦功率的要求。我们研究了几种泵浦配置，发现在采用混合泵浦方案时，性能和功率的折衷效果很好，该方案结合了前向 915 nm 包层泵浦和后向 1480 nm 芯泵浦。利用混合泵浦的实验测量结果，我们训练了一个神经网络模型来预测增益和噪声系数。利用快速而精确的神经网络模型，我们研究了当包层泵浦与磁芯泵浦的功率百分比不同时对性能（增益、噪声系数和总功耗）的影响。

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.
