Abstract
The profile of fiber Bragg gratings (FBGs) utilized in fiber grating prism and other wavelength-selective phased-array beamformers can be optimized using the results of window theory. In this paper, the window formalism is adopted to quantify the relationship between the FBG profile and its spectral selectivity. It is shown how application of optimum and suboptimum windows affects the reflectivity, bandwidth, and sidelobe level of FBG. Also, the impact of taper on the group-delay nonuniformity, an essential issue for true time delay processors, is discussed.
