摘要：
A tunable microwave photonic filter based on mode-locked fiber laser (MLFL) is proposed and experimentally demonstrated. The MLFL can be operated as a single carrier source or a multiple-optical-carrier source by adjusting the polarization state of MLFL, different transfer functions are realized. The filter based on the multiple-optical-carrier source shows a single-passband filter and an improved noise figure, and the tunability is achieved by varying the polarization state of MLFL. By cascading with an infinite impulse response (IIR) filter realized by a fiber ring structure, the filter shape can be varied by matching the single-passband filter and the IIR filter.
