-We propose a novel approach to realizing all-optical
microwave filtering using an array of fiber Bragg gratings with
identical reflectivities. The filter tapping coefficients are determined
by the spectrum profile of a broadband light source and
the central wavelengths of the gratings. Since the fiber Bragg
gratings have identical reflectivities, the characteristics of the
gratings with high uniformity are possible, which simplifies the
fiber Bragg grating fabrication and reduces the implementation
error. In addition, the spectrum profile of the broadband light
source can be controlled using an optical filter, which could be used
to control the filter coefficients to suppress the filter sidelobes. A
microwave filter using four fiber Bragg gratings is experimentally
implemented.
