A pulse of light temporally dilates or compresses because of dispersion as a result of the fact that in all media except vacuum, the group velocity of light depends on its wavelength. This phenomenon occurs, of course, in every travelling wave that carries energy, and in the context of light, has been exploited, utilized, or mitigated ever since short-pulse lasers emerged. Mode-locked lasers, for instance, depend critically on the “dispersion-map” of the path in which light travels in a laser cavity. Traditionally, optical techniques to control or compensate dispersion comprised devices that would provide wavelength-dependent delays, such as bulk-optic diffraction gratings or prisms.
