摘要

High spatial resolution information of the rare-earth dopant distribution in optical fibers enriches our understanding of the fiber manufacture processes and enables improvement in the design of active photonic devices including optical fiber lasers and amplifiers. Here, data from an investigation of the backscattered fluo-rescence signal off the end-face of an erbium (E~(3+)) doped silica optical fiber obtained with a near-field scanning optical microscope (NSOM) are presented. It has been recently confirmed via a theoretical model that information about the relative Er~(3+) ion distribution in fibers can be inferred by simply monitoring the fluorescence signal onginating from the de-excitation of specific energy levels in the investigated samples. A comparison of the Er~(3+) ion distribution profiles extracted from the fluorescence measurements acquired through the NSOM system with those obtained from the application of a powerful analytical ion probe is also presented.
