Analysis of clustering in Eu(DBM)3Phen-doped polymer optical fiber by Effective-Medium Approximation

摘要

The Eu(DBM)3phen-doped polymer optical fiber slice was prepared, and the population of Eu3+ ion was up to 1.0 wt.-%. The chromatic dispersion and absorption characteristics of fractal clusters of Eu3+ ions in Eu(DBM)3phen-doped POF slice were explored. The dielectric components homogeneously and inhomogeneously doped circumstances of this kind of POF slices were studied and their transmissions were analyzed and compared theoretically. Using near-field scanning optical microscopy (NSOM), the near-field light intensities of this kind of POF slice were measured, and agreement was obtain between experiment and theory. The result indicates that the clustering in this kind of POF is not obvious.
