Abstract

Optical fiber communication has been the most versatile and revolutionary medium of communication that has helped connect millions of people across the globe. These traits have seen tremendous development in the sector of optical fiber communication. There are now many desired qualities expected out of an optical fiber communication such as large transmission capacity and a smaller amount of loss. Communication systems operating with higher transmission rates have found an essential role of non-linear fiber optics. The behavior of light in non-linear media is described by non-linear optics. Cross-phase modulation (XPM) and self-phase modulation (SPM) are a few non-linearities occurring in the optical fiber. Non-linear effects reduce the performance of optical fibers. In this paper, a comparative study of non-linear effects in erbium-ytterbium co-doped fiber is reviewed using simulation. The results are compared with optical systems utilizing normal fiber. The benefits of using Er-Yb fiber have been demonstrated by analyzing effective systems comprising the Er-Yb co-doped fiber and their ability to mitigate the non-linearities.

Highlights

The rapid development of erbium (Er)-doped optical fiber amplifiers (EDFA) in the 1550-nm band has greatly improved different Er- and ytterbium (Yb)-doped fiber amplifiers (EYDFAs) and 1550-nm EDFAs.[1]
EYDFs co-doped with Yb attain several advantages over erbium-doped fibers (EDFs) with benefits such as higher Er concentration and, significantly, a bandwidth and a greater absorption intensity around 980 nm
We have investigated the properties of Er-Yb fiber by comparing it with other similar systems consisting of

Summary

Introduction

The rapid development of erbium (Er)-doped optical fiber amplifiers (EDFA) in the 1550-nm band has greatly improved different Er- and ytterbium (Yb)-doped fiber amplifiers (EYDFAs) and 1550-nm EDFAs.[1]. The free-space wave number is denoted by k0 and contains the value of 2 ∕ , λ is the optical signal wavelength, and L denotes the fiber length.[17] Intensity dependence of phase fluctuations causes different phase shifts in different parts of the pulse leading to frequency chirping.
