Characterization and testing of novel single core phosphate fibers

Abstract

This work is devoted to the study of novel optical fibers doped with Er3+ ions. Fibers were drawn from the phosphate glasses with different compositions. One of the optical fibers was drawn from a heat-treated preform in order to grow Ag nanoparticles while another fiber was drawn from NaYF4: Er3+, Yb3+ nanoparticles containing glass preform. Before discussing the changes in the shape of the emission band at 1.5 μm when in contact with N-Methylaniline, the analysis of the composition and of the structure of the fibers are presented.
