摘要

我们提出了一种在1064nm处具有~ 40μm芯的超大模面积紧凑型杂化多沟光纤。在实际弯曲半径为7.5cm时，沟槽高折射率圆弧可实现1300μm2的模面积。谐振环和沟槽间隙有效地保持单模工作和弯曲损耗约束。

Extremely large mode-area compact hybrid multi-trench fiber with controlled leakage loss

We propose an extremely large mode-area compact hybrid multi-trench fiber with ∼40μm core at 1064nm. High-index arc in trench helps to achieve modearea of 1300μm2 at a practical bending radius of 7.5cm. Resonant rings and trench gaps maintain effectively single-mode operation and bending loss constraints.
