Abstract in English
Pulses suffer from changes in time and space when it propagates through matter, like
the positive Group Velocity Dispersion (GVD) which increases the pulse duration and
disperses its components ,this appears a2s a result of the second derivative of phase with
respect to frequency. We show in this article the possibility of a compensation way to
shorten the pulse duration based on negative GVD.
