2. Four-wave mixing process
2.1 Reminder of the basic physical processes involved
2.1.1 Group speed chromatic dispersion
Optical fibers are generally made mainly of silica glass, which is a dispersive material, meaning that its refractive index depends on wavelength. As a result, each spectral component of a pulse travels at a different group velocity from the others: this is chromatic group velocity dispersion. This phenomenon is characterized by a change in the temporal profile of the pulse as it leaves the propagation medium
