摘要

空分复用(SDM)铒/镱(Er3+/Yb3+)共掺七芯光纤放大器是适应光纤传输系统容量快速发展的一种有潜力的配置方式。为了提高SDM-WDM系统的传输容量和增益特性，提出并仿真了一种基于SDM和波分复用(WDM)铒/镱(Er3+/Yb3+)共掺七芯光纤放大器的增强架构技术。所提出的架构使我们能够在大频带内获得超过49 dB的峰值增益和大于20 dB的增益，并且噪声最小，在该放大带宽内噪声低于6 dB。

Theoretical Analysis of Space and Wavelength Division Multiplexing Er3+/Yb3+ Co-Doped Seven-Core Fiber Amplifier

Space division multiplexing (SDM) Erbium/Ytterbium (Er³⁺/Yb³⁺) co-doped seven-core fiber amplifier is one of the potential configurations used to accommodate the rapid development of the capacity of optical fiber transmission systems. To increase the demand transmission capacity and enhance the gain characteristics limited by only Erbium-doped multicore fiber amplifier for SDM-WDM system, we propose and simulate an enhanced architecture technology based on combining SDM and wavelength division multiplexing (WDM) Erbium/Ytterbium (Er³⁺/Yb³⁺) co-doped seven-core fiber amplifier. The architecture proposed allows us to obtain a peak gain over 49 dB and a gain greater than 20 dB in a large band with a minimum noise, which is lower than 6 dB in this amplified bandwidth.
