摘　　要：光纤滤波器在光纤通信和光纤激光器制作中发挥着重要的作用。通过对耦合理论分析,利用宽带光源和光谱仪构建测试系统,测试了耦合型光纤滤波器光谱响应,研究了不同拉锥周期与透射波长的关系。实验表明,拉锥周期越长,透射波长峰值间隔越密集,光谱响应更加敏感。因此可以利用这一特性制作不同透射波长、不同滤波间隙的光纤滤波器。Optical fiber filters play an important role in optical fiber communication and optical fiber lasers fabrication. Based on coupling theory analysis, spectral response of coupling optical fiber filters is tested and the relationship between tapered cycle and transmission wavelength is researched by broadband light source and spec-trometer building and testing system. Experimental results show that the longer tapered cycle is, the denser peak intervals of transmission wavelength is and the more sensitive spectral response is. So optical fiber filters with different transmission wavelength and filtering gap can be produced according to the property.
