This paper proposes the interferometric method for arrays inscription of type I Bragg gratings on the unified segment of the standard telecommunication single-mode optical fiber, using preliminary inscription of the gratings with low diffraction efficiency. The accuracy of setting the Bragg resonance wavelength of each individual diffraction structure is at least 50 pm with the reflection coefficient close to 100%. Also, the results of chirped fiber Bragg gratings arrays inscription in a fiber with a high content of germanium dioxide (GeO₂) in the core are obtained. An analysis of the spectral characteristics of the inscribed periodic structures of modulation of the refractive index is made.

本文提出了一种采用低衍射效率的光栅初步刻划的方法，用于在标准电信单模光纤统一段上的I型布拉格光栅的阵列刻划。设置每个衍射结构的布拉格共振波长的精度至少为50 pm，反射系数接近100％。而且，获得了在纤芯中具有高含量二氧化锗（GeO ₂）的光纤中chi光纤布拉格光栅阵列题字的结果。对内接的折射率调制的周期性结构的光谱特性进行了分析。
