|
摘要
梳状滤波器在波分复用系统和多波长激光器等方面有重要应用。利用光纤光栅实现的梳状滤波器因反射或透射特性优良、附加损耗小、体积小以及易与全光纤集成等优点在光电子以及光纤通信领域具有重要作用。本文对带有对称啁啾光纤光栅的Sagnac环梳状滤波器结构进行了改进,提出了带有两个相同啁啾光纤光栅的梳状滤波器结构,讨论了新型梳状滤波器的滤波特性,分析了光栅长度、调制深度、啁啾参数等因素对滤波器滤波特性的影响,讨论了新型梳状滤波器的色散补偿特性。设计搭建了实验平台,获得了插入损耗小,通带间隔均匀的梳状透射谱。本论文克服了以往光纤光栅Sagnac环梳状滤波器的不足,具有使用价值。
Comb filter has very important applications in the respect of WDM (wavelength division multiplexing), multiwavelength lasers and so on. Comb filter with fiber bragg grating has received great attention because of its choiceness capability of reflection or transmission , low insert loss ,small size and easy integration with fiber. We improve a comb filter construction which symmetric chirped fiber grating inserted into a Sagnac loop in this thesis and Proposed a new structure witch the same two fiber bragg grating inserted into comb filter.the characteristic of this new comb filter is studied. The relation between the frequency response and the parameters of the comb filter, such as fiber length, modulate deepness and chirp parameter is discussed. analyse the dispersion compensate of chirped fiber gratings. Design and set up Test bed and obtain transmitted spectrum with low insert loss and symmetrical intervals in experimentation. Work in this thesis conquer the shortcoming of fiber bragg grating Sagnac loop .it have practical value.
