摘要

提出了一种新型的抗弯曲大模场面积光纤方案——双沟槽辅助型扇形瓣状光纤。与传统的扇形瓣状光纤及单沟槽辅助扇形瓣状光纤相比,该结构具有更大的模场面积和更好的高阶模抑制能力。研究结果表明:在弯曲半径为20 cm,波长为1.55 μm时,光纤的有效模场面积可达1096 μm 2,高阶模与基模损耗比大于100;此外,所提出的光纤对弯曲方向不敏感,弯曲方向在[-180°,180°]范围内变化时,光纤性能保持稳定。

Abstract

A novel double-trench-assisted fan-segmented cladding fiber (SCF) is proposed and researched. Compared with traditional fan-SCF and single-trench-assisted fan-SCF, the proposed fiber structure has a larger mode area and better high-order mode (HOM) suppression. Numerical investigations show that, when the bending radius is 20 cm, the effective mode area of the fundamental mode (FM) reaches up to 1096 μm 2 and the loss ratio between HOM and the FM is greater than 100 at a wavelength of 1.55 μm. In addition, the proposed fiber structure is insensitive to the bending orientation and its properties remain stable with a bending orientation ranging from -180° to 180°.
