Group velocity dispersion is the phenomenon that the group velocity of light in a transparent medium depends on the optical frequency or wavelength.

Group Velocity Dispersion refers to the phenomenon where the velocity of light in a dispersive medium is dependent on its wavelength, resulting in a ...

So the group velocity equals the phase velocity only when dn/dω = 0, such as in vacuum. But n usually varies with ω in materials. v v / 1 g dn. n d.
