摘　　要：针对传统的基于电子电路的信号处理带宽和速度不能满足日渐增长的宽带信号需求的问题,在对微波光子技术充分调研和分析的基础上,提出了基于微波光子积分器的信号处理概念和相应器件功能,总结了近年来微波光子积分器的研究进展及其性能参数并指明了微波光子积分器在宽带微波信号处理方面的重要应用以及相较于电子处理器的明显优势。最新研究结果表明,微波光子积分器的时间带宽积可达到28 800,比传统电子器件高2个数量级。Due to the fact that the bandwidth and processing speed of the traditional electronic circuits cannot meet the demand of signals with broad bandwidth, a concept of photonic signal processing technology based on microwave photonic integrator has been proposed.A summary of microwave photonie integrators is presented and different proposals of photonie integrators are analyzed.The ap- plications of microwave photonic integrators in signal processing are pointed out and a comparison between the photonic integrator and its electronic counterparts is made.A new research report indicates that the product of time-bandwidth of microwave photonic integrator reaches 28 800,which is 2 times larger than that of the electronic processors.
