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。
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.
