Enhancement the Propagation Properties of Optical Fiber Communication Links Using Core Doped Optical Fibers

Abstract

The increasing applications for modern optical fibers present significant challenges to the material properties and the processing technology of fiber optics. These types of optical fibers had many applications in optical fiber communication system and sensing devices. This work studied the transmission properties of core-doped single-mode fiber with different materials doping. Two doping materials were used, germanium and thallium, with different communication link lengths (1 and 15) meters. This work studied Full Width of Half Maximum (FWHM) and dispersion. The results clearly show that the doping material decreases the broadening of the Gaussian propagation pulse and thus decreases dispersion. This influence was more apparent in optical fibers doped with thallium than germanium.
