摘　　要：采用相位掩模板扫描法,在单模光敏光纤中制备了中心波长为1541.86nm,菲波纳契序数为0～9的准周期超结构光栅.通过模拟引入相移过程中纤芯折射率的改变对制作参量进行了优化.传输矩阵分析与实验结果均表明,该超结构光纤光栅的透射谱呈现分形结构,在中心波长附近有六循环和自相似特性.所制备超结构光栅可作为C波段分形结构滤波器件在光通信和全光集成领域得到应用.Quasi-periodic superstructure fiber Bragg gratings （SFBG） of 0~9 Fibonacci order with the central wavelength 1 541.86 nm were written into single mode photo-sensitive fiber by phase-mask scanning technique. The fabrication parameters were optimized by simulating the UV induced refractive index change in the fiber core. Both theoretical and experimental results show that the transmission spectra were multi-fractal, self-similar and the transmission coefficients have six-cycle property. The fabricated SFBG can be served as C-band multi-frequency optical device in optical integrated circuits and optical communication system.
