A pulse of light spreads in time as it propagates in a fiber due to the physical phenomenon called dispersion. While dispersion can be deleterious in optical communications systems, it can also be exploited to manage the temporal and spectral shapes of pulses and their interactions with other pulses. Much of dispersion control is realized in...
