Comparative Analysis of Side-Illumination Methods of Measurement of Emission Decay of Fluorescent Polymer Fibers

摘要

The fluorescence decay constant of a fluorescent polymer optical fiber is measured by two different side illumination methods. Comparative analysis of these methods is performed. It is shown that the difference in the measured parameters is caused by different conditions of energy exchange between the core, cladding, and radiation modes of the fiber waveguide.
