Abstract :
We report on a novel technique for the design of fiber gratings whose reflection characteristic closely approximates the ideal rectangular linear phase filter. The technique is based on the design of a suitable grating period variation, following the apodization function, in order to ensure the Bragg condition to remain constant along the grating length.
