abstract = {In this paper we present the simulation results of two different
methods of grating engineering (Genetic Algorithm and Discrete
Layer Peeling) used for the synthesis of Bragg Gratings with a
negative Group Time Delay. The physical structures of the
resulting gratings, as well as their reflection spectra, are
displayed for different initial parameters. These gratings could
be employed (as it will be demonstrated) as cavity reflectors for
the generation of a continuum laser emission by other means than
those of nonlinear optics.}
