Optimization of large-mode-area tapered-index multi-core fibers with high differential mode bending loss for Ytterbium-doped fiber applications

摘要

Large-mode-area (LMA) tapered-index multi-core fibers (MCFs), made by hexagonal stacking of up-doped cores in silica, are optimized through a genetic algorithm (GA) for high fundamental mode (FM) effective area and high differential loss with higher-order modes (HOMs) in bending condition.
