| 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1 541.86 nm,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.

| Abstract: | 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 s... |
