摘要：

This work presents a novel microwave photonic filter using a distributed feedback (DFB) laser. In the proposed filter, the DFB laser is modulated directly by means of the radio-frequency signal to provide a multi-wavelength laser source (MWLS). The proposed filter can thus provide precision for adjusting the central frequency. Moreover, the calculated and experimentally measured responses correlate well with each other. The above results demonstrate that the proposed filter is highly promising for use in practical applications.
