7. Glossary
four-wave mixing
Non-linear process of order 3 involving two pump waves, a signal wave and a complementary wave. When phase-matched, it transfers energy efficiently from the pump to the signal and complementary waves.
phase self-modulation
3rd-order non-linear effect involving a single wave, responsible for spectral broadening of the incident pulse.
frequency drift
Characteristic of a pulse with spectral components distributed over time.
group speed dispersion
Generally noted β 2 , variation of group velocity with frequency or wavelength. It is responsible for frequency drift.
zero-dispersion wavelength
Wavelength delimiting...
