- Abstract
The nonlinear equations of Gaussian apodized and cosine shapes of fiber Bragg gratings (FBGs) are solved for quasi-pulses by using a simple numerical approach. We showed that there is a switching action for these structures related to input pulse power, and the required switching power for cosine shape FBG is 30% less than that needed for apodized FBG. Also, for two configurations, attenuation of the pulse amplitude at the fiber ends is less respect to the uniform gratings. In fact, we have almost constant pulse amplitude and there is attenuation just at the fiber centre where the grating coupling coefficient is high. Our numerical method is applicable to non-solitary pulses too.
