The paper presents a novel microwave transversal filter based on spectral tapping of broadband light using fiber Bragg grating array. This structure has the advantages that it can achieve arbitrary tap weighting by controlling the reflectivity of the grating array in the fabrication, is readily scalable to a large number of taps without insertion loss increasing, and is tunable by adjusting the center wavelengths of the gratings to adjust the basic time delay provided by a dispersive element. Experimental results demonstrate our conclusions in the paper.
