英文摘要： Microwave photonic filter (MPFs) are important contents in study of microwave photonic processing. To meet the exigent requirements of radio over fiber and military radar systems, and overcome the limitations in programmablity and reconfiguration of conventional processors, we propose techniques to flexibly process microwave signals by optical source engineering. In this proposal, we plan to carry out theoretical investigation, experimental study, and application implementation of MPFs based on optical source engineering. The influence of various optical source parameters on the transfer function of the MPF will be deduced and fully understood. Flexible control and processing of microwave signals will be realized by optical source engineering; programmable and reconfigurable MPFs with high performance will be obtained. High resolution fiber sensors will also be developed using microwave photonic filtering technique.We expect that a comprehensive and intensive understanding of MPFs based on optical source engineering can be achieved, and the limitaion in programmablity and reconfiguration of conventional processors can be overcomed. Moreover, we hope advantages and potentials of this kind of MPFs can be further excavated through these work.Therefore, it is of great importance to carry out the research proposed in this proposal.
