This article focuses on the parameters that affect available bandwidth in optical fibers, and the dispersion mechanisms of various fiber types and non-linear effects. Dispersion describes the process of how an input signal broadens out as it travels down the fiber. There are several types of dispersions that we will cover. We’ll also take a cursory look at other important nonlinear effects. Later, in the s, nonlinear effects in fibers were used for pulse compression and optical switching [ 9, 10, 11, 12, 13, 14, 15, 16 ].
A change in the doping material of the fibers (using rare-earth elements) made it possible to create all-optical amplifiers, leading to a revolution in fiber-optic communication. The nonlinear part of the refractive index significantly affects modern lightwave systems due to the long fiber lengths. In particular, it leads to the phenomena of self‐phase modulation (SPM) and cross‐phase modulation (XPM).
Both SPM and XPM produce a phase alteration of the pulse, which leads to a change in its spectrum. SPM determines a broadening of the pulse spectrum due to its own intensity. SPM is a nonlinear phenomenon affecting. Download as PDF. Set alert. About this page. Nonlinear Optics. Halina Abramczyk, in Introduction to Laser Spectroscopy, Publisher Summary.

Nonlinear propagation of signals in single-mode fibers is well understood, and is typically observed by measuring the temporal profile or optical spectrum of an emerging signal. In multimode fibers, the nonlinearity has both a spatial and a temporal element, and a complete investigation of the interactions between propagating modes requires resolving the output in both space and time.
