Design Optimization and Performance Evaluation of ER Doped and ER-YB Co-Doped Fiber Amplifier Considering Ion-Ion Interaction Effect
Efficiency of fiber amplifier can be increased by doping with rare earth elements but ion-ion interaction effect
limits the gain. This paper reviews the design and performance of Er and Er-Yb doped fiber amplifier.
Keyword- Er-doping, Er-Yb co-doping, ion-ion interaction effect, upconversion effect.
