Multi-tap microwave photonic filter using a sampled-chirped fiber Bragg grating based multi-wavelength erbium-doped fiber laser

We have presented and experimentally demonstrated a multi-tap microwave photonic filter. The filter is based on a multi-wavelength erbium-doped fiber laser which is inserted with a samplechirped fiber Bragg grating. The near-Gaussian profile distribution of the multi-wavelength has been created for the fiber laser to generate the multi-tap filter. We have also demonstrated the reconfigurability feature of the multi-tap filter.
