Two approaches are proposed for generating optical arbitrary waveforms using sampled fiber Bragg gratings (FBGs). The manipulation of the optical spectrum of an input pulse is achieved by a sampled FBG which is fabricated using a novel technique based on the reconstruction-equivalent-chirp (REC) method. The key advantage of the REC technique is that it can produce FBGs with various phase profiles using a fabrication system having only micrometer precision. Two examples for the generation of Gaussian doublet pulses are demonstrated, which would find applications in ultra-wideband over fiber systems.
