摘要

本文提出了一种基于多阶跃折射率纤芯结构的大模面积单模光纤。多阶折射率磁芯增加了模场面积（MFA）。梯形折射环结构和沟槽层结构保证了光纤保持有效的单模状态。采用有限元法对结构进行了分析。数值计算结果表明，该光纤在弯曲半径为10 cm时仍能保持有效的单模状态。在2.0 μm波长处，MFA达到2578.136 μm2。在基频模式下，漏损（loss）为0.076 dB/m。该光纤结构还具有开发1.55 μm波长高性能LMA单模光纤的潜力。此外，纤维结构的圆对称性使其对弯曲方向不敏感。这些特性表明该光纤在高功率激光系统中具有很大的应用潜力。

All Solid Multistep-Index Core Large Mode Area Single-Mode Fiber

In this paper, a large-mode-area (LMA) single-mode fiber based on multistep-index core structure is proposed. The multistep-index core increases the mode field area (MFA). The trapezoidal refractive ring structure and the trench layer structure ensure the fiber maintains effective single-mode regime. The structure is analyzed using the finite element method (FEM). Numerical results show that the proposed fiber is capable of maintaining effective single-mode regime at a bending radius of 10 cm. The MFA reaches 2578.136 μm² at the wavelength of 2.0 μm. The leakage loss (Loss) is 0.076 dB/m for fundamental mode (FM). The fiber structure also has the potential to develop LMA single-mode fiber with high performance at the wavelength of 1.55 μm. Furthermore, the circular symmetry of the fiber structure makes it insensitive to bending direction. These features indicate the proposed fiber has great potential in the application of the high-power laser system.
