Study On Erbium-doped Optical Fiber Amplifier Glass

In1930s, it is argued “optical communication will substitute microwavecommunication and to be the main type of communication”. Today, opticalcommunication is becoming mature, optical communication press way is playing acritical role, many countries hold optical communication as the national developingstrategy. The optical communication technique is developing rapidly due to the need ofthe public and the advantage of optical communication itself.Silicate glasses is composed by silica, it is a type of advanced glasses since it hasgood chemical stability and thermal stability, meanwhile, it is well compatible withcurrent widely used optical communication system, this dissertation set silica as basematerial, dopes bismuthate and antimonite, then dopes rare earth erbium ion, and testsit’s optical properties, accomplishes increasing its absorption and emission spectra ininfrared section, this dissertation has also accomplished analyzing the change of infraredsection with changing concentration of erbium ion. This dissertation tries to content thesocial needs of optical communication.The purpose of transport network in the future is to build AON(all optical network),that is to say, all of AN(access network), MAN(metropolitan area network) andBN(backbone network) is build with optical fibre instead of copper wire. Exploring newoptical amplifier materials, researching and enhancing the properties of rare earth dopedoptical amplifier will impact on optical communication profoundly, this dissertationindicate to approach this purpose.
