An Overview of <str<strong>on</strong>g>Fiber</str<strong>on</strong>g> <str<strong>on</strong>g>N<strong>on</strong>linearities</str<strong>on</strong>g><br />
• g is real => gain or loss. Parametric<br />
interacti<strong>on</strong> between phot<strong>on</strong>s <str<strong>on</strong>g>and</str<strong>on</strong>g> ph<strong>on</strong><strong>on</strong>s<br />
– Stimulated Brillouin scattering<br />
– Stimulated Raman scattering<br />
• g is imaginary => phase modulati<strong>on</strong>.<br />
Modulati<strong>on</strong> of refractive index by light<br />
intensity fluctuati<strong>on</strong><br />
– Self phase modulati<strong>on</strong> (SPM)<br />
– Cross phase modulati<strong>on</strong> (CPM)<br />
– Four-phot<strong>on</strong> mixing (FPM)<br />
