In this letter, novel fiber Bragg gratings are proposed, combining the present technology of fiber Bragg gratings with the theory of pseudonoise (PN) sequences. The principal goal of this work is to design fiber Bragg gratings in which it is possible to control their spectrum, especially with respect to their bandpass characteristics. The reflectivity spectra of these devices show spectral characteristics similar to direct‐sequence spread spectrum. Numerical examples demonstrate these broadband spectral properties. ©2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 244–247, 2000.
