中文摘要：
本文主要对拉锥型啁啾光纤光栅滤波器进行详细的理论分析和实验研究．结合传输矩阵法，谐振理论和耦合模理论，深入细致地分析了啁啾光纤光栅自身参数（光栅长度，折射率调制幅度，啁啾系数），拉锥参数和锥区损耗对拉锥型啁啾光纤光栅滤波器透射谱的影响，并研究拉锥对啁啾光纤光栅各波长反射率影响．在此基础之上进行相应的数值仿真及实验验证，数值仿真与实验结果基本一致．
英文摘要：
Tapered chirped fiber grating filter is analyzed from the detailed theoretical and experimental studies. The transmission spectrum of tapered chirped fiber grating filter is influenced by the parameters and loss of chirped fiber grating （length, refractive index modu- lation, chirp coefficient） and taper after examined by the transfer matrix method and resonance theory combined with coupled-mode theory. We study the influence of the chirped fiber grating wavelength reflectivity by tapering, and make the corresponding numerical simulation and experimental verification based on the above theories. Numerical simulation result is consistent with the experimental data.
