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 />
• The n<strong>on</strong>linearities in silica fibers can be<br />
divided into two categories:<br />
1. Stimulated scattering (Brillouin(<br />
<str<strong>on</strong>g>and</str<strong>on</strong>g> Raman),<br />
gives rise to intensity dependent gain or loss<br />
2. Effects arising from the n<strong>on</strong>linear index of<br />
refracti<strong>on</strong>. Gives rise to an intensity dependent<br />
phase of the optical field leading to distorti<strong>on</strong>,<br />
cross modulati<strong>on</strong>, etc.<br />
