Abstract

We design for the first time a dual-core hollow core negative curvature fiber mode-selective coupler (HCNCF-MSC) in the 1 μm band. The designed HCNCF-MSC consists of two structures, and we have analyzed the performance of these two structures separately. The shortest device length of HCNCF-MSC-A is 3.2 cm, achieving a mode conversion efficiency higher than 75 % within the transmission wavelength range of 0.8–1.7 μm. HCNCF-MSC-B can achieve mode conversion under four different core diameters, with the shortest device lengths being 4.5 cm, 3.8 cm, 3.0 cm, and 2.4 cm, respectively, and it realizes a mode conversion efficiency greater than 80 % within the transmission wavelength range of 0.8–1.7 μm.

1 μm波段双芯空心负曲率光纤宽带模式选择耦合器

首次在1 μm波段设计了双芯空心负曲率光纤模式选择耦合器（HCNCF-MSC）。设计的HCNCF-MSC由两种结构组成，我们分别对这两种结构的性能进行了分析。HCNCF-MSC-A的最短器件长度为3.2 cm，在0.8 ~ 1.7 μm的传输波长范围内，模式转换效率高于75% %。HCNCF-MSC-B可以在4种不同芯径下实现模式转换，器件最短长度分别为4.5 cm、3.8 cm、3.0 cm和2.4 cm，在0.8 ~ 1.7 μm的传输波长范围内，模式转换效率大于80% %。
