Frequency modulation spectroscopy of erbium–cerium codoped fluoride glasses for optical amplifiers (original) (raw)

Optical Materials, 2003

Abstract

We report frequency modulation spectroscopy measurements performed on erbium doped fluoride glasses: PZG (39% PbF2, 19% ZnF2, 42% GaF3) and ZBAC (57% ZrF4, 34% BaF2, 5% CeF3, 4% AlF3). For the ZBAC glass, no changes of lifetime in channel waveguides versus bulk were observed as well as no pump power dependence from 1 to 100 mW. On the contrary, for
