摘　　要：利用耦合模理论分析了全光纤Mach-Zehnder干涉结构的梳状滤波器的输出功率谱和滤波特性。用熔融拉锥设备和特定的制作工艺,研制成中心波长间隔为0.8nm的全光纤梳状滤波器.它具有附加损耗小,偏振不灵敏,工艺重复性好等优点.The output power spectrums and filter characteristics of a comb filter with Mach-Zehnder interferometer using coupled-mode theory is analysed in this paper. All-fiber comb filters with a wavelength spacing of 0.8 nm are made by using fused taper equipment and special technic. They have low insertion loss, low polarization sensibility, better repeatability on technic.
