Abstract

Our proposal is to create a design for a three-mode erbium-doped fiber amplifier (3M-EDFA) that is specifically intended for use in a system that combines mode division multiplexing (MDM) and wave division multiplexing (WDM) techniques. After the efficacious completion of concurrent fiber parameters and innovative branching matrix multi-optimization for erbium profile. The 3M-EDFA system, with cladding pump power, demonstrates remarkable performance, achieving a gain surpassing 24.152 dB and a noise figure below 4.462 dB for all 48 channels evenly distributed across the LP₀₁, LP₁₁, and LP₂₁ signal modes. Across all the channels, 3M-EDFA exhibits gain excursion (GE) and noise figure excursion (NFE) of 0.663 dB and 0.428 dB, respectively. Furthermore, it is noteworthy that the pinnacle values attained for the differential modal gain (DMG) and differential modal noise figure (DMNF) within the wavelength range of 1543 nm to 1558 nm are a mere 0.0563 dB and 0.23 dB, respectively. Our proposed FM-EDFA system possesses the desirable characteristics of minimal excursion in both gain and noise, making it an excellent choice for future high-capacity MDM-WDM networks.

针对MDM-WDM系统超低增益和NF偏差的3M-EDFA设计

我们的建议是创建一个三模掺铒光纤放大器（3M-EDFA）的设计，该放大器专门用于结合模分复用（MDM）和波分复用（WDM）技术的系统。在有效地完成了并行光纤参数和创新分支矩阵对铒剖面的多重优化后。具有包层泵浦功率的3M-EDFA系统表现出卓越的性能，在LP01、LP11和LP21信号模式中均匀分布的所有48个通道中，增益超过24.152 dB，噪声系数低于4.462 dB。在所有通道中，3M-EDFA的增益偏移（GE）和噪声系数偏移（NFE）分别为0.663 dB和0.428 dB。此外，值得注意的是，在1543 nm至1558 nm波长范围内，差分模态增益（DMG）和差分模态噪声系数（DMNF）的峰值值分别仅为0.0563 dB和0.23 dB。我们提出的FM-EDFA系统具有增益和噪声最小偏移的理想特性，使其成为未来大容量MDM-WDM网络的绝佳选择。
