Abstract
To design a compact erbium-doped fiber laser, a high-concentration
erbium-doped fiber (EDF) is needed. However, increasing the erbium ion
(Er3+) concentration can reduce the EDF performance via the
Er3+-Er3+ interaction. In this Letter, we
investigate the Er3+-Er3+ interaction effect by
designing a tunable erbium-doped fiber-ring laser (EDFRL). This is the
first time (to the best of our knowledge) that someone has considered
different numbers of ions per cluster and simulated the EDFRL output power
degradation due to ion–ion interaction. If the number of ions in the
cluster is increased, the lasing output power will decrease accordingly.
The most dominant effect is seen in the 1530 nm wavelength region, where
the EDF shows a higher signal absorption compared to the other wavelength
region. Moreover, a comparison has been done for lasing performance
analysis with different dopant ion concentrations. The comparison results
show that a higher dopant concentration is advantageous for
longer-wavelength lasing.
