✦ Synopsis
The profile of fiber Bragg gratings FBGs utilized in fiber grating prism and other wa¨elength-selecti¨e 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 selecti¨ity. It is shown how application of optimum and suboptimum windows affects the reflecti¨ity, bandwidth, and sidelobe le¨el of FBG. Also, the impact of taper on the group-delay nonuniformity, an essential issue for true time delay processors, is discussed.
