After the pioneering experiments by Craig Poole from Bell Labs in 1993, an application that faded away but saw a re-emergence in 2000-2003 was higher order mode dispersion compensation. In this scheme, mode converters are used to selectively propagate the signal in a higher order mode of a few-mode fiber. variational principle, including second-order dispersion, self-focusing, diffraction and second-order dispersion of the mirrors [18, 19]. The focus of this work is to extend the one-dimensional model, which describes the temporal dynamics, to include higher order material dispersion as well as the detailed mirror and

This PhD thesis considers higher order modes (HOMs) in optical fibers. That includes their excitation and characteristics.

OSA A passively-modelocked Yb-doped figure-eight. strictly, dispersion compensation should be understood as a method for canceling the chromatic dispersion of some optical element(s), whereas dispersion management is more generally the use of tailored dispersion properties in order to enhance some function. examples of dispersion management in different situations are:, dispersion. for example, by searching for a speciп¬ѓc r,h conп¬ѓguration (and proper selection of the prism material), one may be able to compensate for both gdd and third order dispersion, which is important for management and generation of extremely short (sub 50fs) pulses. the refraction angle оґоё).

вЂўThe more photons (i.e., the higher the order) the weaker the effect, however. Very-high-order effects can be seen, but they require very high irradiance. Also, if the photon energies coincide with the mediumвЂ™s energy levels as above, the effect will be stronger. Nonlinear-optical processes are often referred to as: "N-wave-mixing processes" the group velocity dispersion and the higher-order dispersion, in different pulses. In order to avoid dispersive effects on the pulse transmission, in the linear regime, two dispersion management schemes are presented: and common dispersion management in solitons systems, so that the jitter effect is minimised. 1 - Introduction

Dispersion of third and higher order is called higher-order dispersion. When dealing with very broad optical spectra, one sometimes has to consider dispersion up to the fourth or even fifth and sixth order. Ultimately, the concept of Taylor expansion loses its value in this regime, where many dispersion orders have to be considered.
