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

shorten the pulse duration based on negative GVD.
