A tunable and reconfigurable multi-tap microwave photonic filter with negative coefficients is proposed and demonstrated. The baseband resonance is eliminated by an electro-optic phase modulator combined with a dispersive medium. A Mach-Zehnder modulator (MZM) is used to get a multi-wavelength source out of a single laser diode. The free spectral range and spectral response of the microwave photonic filter is tuned and reconfigured by controlling the microwave signal and the bias voltage applied on the MZM. Experimental results show the enhanced flexibility of the present microwave photonic filter.
