多芯光纤放大器技术发展现状及展望
Development Status and Prospect of Multi-Core Fiber Amplifier Technology
摘要
Abstract
Multi-Core Fiber Amplifier(MCFA),as the core components of Space-Division Multiplexing(SDM)systems,play a crucial role in enhancing the transmission capacity and energy efficiency of optical communications.This paper reviews its key technologies,including fiber design and pump efficiency enhancement,and analyzes the advantages of these approaches.By opti-mizing core arrangement and refractive index profiles,high bandwidth and low crosstalk can be achieved.The energy utilization can be significantly enhanced by improving the pump efficiency.Addressing current challenges in crosstalk suppression,thermal management,and cost reduction,the paper outlines future development directions such as Three-Dimensional(3D)integration,machine learning-assisted design,and quantum dot-doped fibers.These technologies are expected to overcome existing limita-tions and promote the widespread application of MCFA in high-capacity,low-power optical communication systems.关键词
