微波光子滤波器能够实现在光域内直接对射频信号的处理,并且较易实现可调谐性和传输函数的快速重构,从而成为微波光子学的一个重要研究内容.本文综合评述了不同光源的微波光子滤波器和基于FBG的不同微波光子滤波器结构,并分析比较了各自的功能特点和不足.
For microwave photonic filter can process RF signal directly in the optical domain, its response can be easily tuned and its transfer function can reconfigurate fast, microwave photonic filter become an important research content in microwave photonics. In this paper, we have introduced some filter structures with different light sources and structures based on fiber bragg grating, simply analyzed their function characteristics and shortages.
