The characteristic analysis of microwave photonic filter based on a pair of FBG

在深入研究微波光子滤波器理论的基础上,提出了一种基于FBG对的微波光子滤波器结构模型,对其进行了详细的理论分析,并用MATLAB仿真分析了耦合系数、FBG对的反射率、增益光纤长度和增益对系统传输特性的影响。

Based on the thorough research of the theory of the microwave photonic filter, a kind of microwave photonic filter based on a pair of FBG was put forward,the theory of it was detailed analyzed, and simulated the transmission performance with MATLAB, discussed the coefficient of coupling, the reflectivity of the pair of FBG, the length and the gain of the gain fiber make effect on the transmission characteristics of the system.
