| 摘 要： | 利用光纤布拉格光栅(FBG)对光波长独特的选择特性,将FBG进行标本化,结合光耦合理论对标本化FBG进行模拟分析,设计了标本化FBG型全光希尔伯特变换器。数值模拟结果表明,利用标本化FBG能够实现光信号的希尔伯特变换处理,且其特性随着希尔伯特变换器的阶数的提高而逐渐接近于理想希尔伯特变换特性。

| Abstract: | A novel all optical Hilbert-transformer based on sampled FBG is designed and simulated by using optical coupling theory.The result of simulation shows the signal processing of Hilbert-transformation can be dealt in the all optical domain by employing sampled FBG,and the characteristic of transformer can be improved by increasing the taps of Hilbert-transformer. |
