摘要
针对空心单模Bragg光纤在1.55μm附近表现出非常大的正色散, 研究了包层缺陷层对空心单模Bragg光纤色散的调节作用。利用光学软件FDTD Solutions对缺陷层空心单模Bragg光纤的模式耦合特性进行分析;对比分析普通空心单模Bragg光纤和缺陷层空心单模Bragg光纤的色散曲线;讨论了包层缺陷层结构参数对空心单模Bragg光纤的色散调节作用。
Abstract
The dispersion accommodation technique based on defect layer is reported direct against the large positive dispersion of hollow single-mode Bragg fiber at 1.55μm. The interaction between defect mode and fundamental mode are analyzed by using the optical software FDTD Solutions; Comparative study on the dispersion curves of hollow single-mode Bragg fiber with and without defect layer is done. The defect layers with different parameters are discussed separately.
