摘要

我们报告了一种实现光子微波滤波器的新方法，该滤波器基于500个弱光纤布拉格光栅级联编写，同时绘制5米长的光纤截面。实验证明具有很高的质量因数(Q>1400)。据我们所知，这是非无限脉冲响应MWP滤波器报道的最高Q因子，比迄今为止报道的最佳离散时间横向MWP滤波器高出一个数量级。

Very high Q-factor microwave photonic FIR filter based on a ultralong FBG cascade

We report on a novel approach to the implementation of a photonic microwave filter that is based on 500 weak fiber Bragg gratings written in cascade while drawing a 5m-long fiber section. A very high quality factor (Q>1400) is experimentally demonstrated. To our knowledge this is the highest Q factor reported for a non infinite impulse response MWP filter and is over one order of magnitude higher than the best discrete time transversal MWP filter reported to-date.
