A Comparative Study of SPM and XPM in Er-Yb Co-doped Fiber

Abstract

Optical fiber communication has been the most versatile and revolutionary medium of communication that has helped in connecting 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 that are expected out of an optical fiber communication like large transmission capacity and a lesser amount of losses. Communication systems operating with higher transmission rates have found an essential role of non-linear fiber optics. The behaviour of light in non-linear media is dealt with 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 performances of optical fibers. In this paper, a comparative study of non-linear effects in Er-Yb co-doped Fiber are reviewed using simulation and the results are compared with optical systems utilizing normal fiber. Benefits of utilizing Er-Yb fiber has been demonstrated by analysing effective systems comprising the Er-Yb co-doped fiber and their ability to mitigate the non-linearities.
