Abstract
An all-fiber Faraday rotator array comprising a plurality of Faraday rotating fibers, each having a doping concentration of 55%-85% (wt./wt.) of a rare-earth oxide, and a magnetic tube surrounding the plurality of Faraday rotating fibers is presented. The rare-earth oxide is selected from the group comprising: Pr2O3, Nd2O3, Pm2O3, Sm2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3; Er2O3, Tm2O3, Yb2O3, La2O3, Ga2O3, Ce2O3, and Lu2O3. Additionally, an all-fiber isolator using highly rare-earth oxide doped fibers is disclosed.
