Evaluation of effective area of erbium doped fibers

Anotacija

The effective area of an Er3+ doped fiber of 3% erbium concentration was studied experimentally by the transverse shift measurement method for the excitation of 980 and 1480 nm wavelengths and at the amplification range of 1520–630 nm. Based on experimental results, the fiber effective area was calculated. A comparative analysis and estimation of the results for different wavelengths of an Er3+ doped fiber are given.
