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.
