Abstract

A novel all-optical microwave filter with a frequency response equivalent to a bandpass filter is presented. An electro-optic phase modulator combined with a dispersive device is employed to eliminate the baseband resonance of a typical lowpass filter. A two-tap bandpass transversal microwave filter with a null-to-null bandwidth of 8.8 GHz and a 35-dB notch rejection level is demonstrated.
