Abstract

The use of rare-earth doped optical fibers in space implies to develop waveguides tolerant to the radiation levels associated with a space mission. Erbium (Er)- or Ytterbium/Erbium (Yb/Er)-doped fibers have been shown to be very vulnerable to ionizing radiations especially through the strong increase of their attenuation around the pump and amplified signal wavelengths. In this paper, we investigate by confocal luminescence microscopy the radiation-induced spectroscopic changes on prototype Yb or Yb/Er -doped optical fibers. The tested fibers allow us to provide new insights into the relative influence of the P, Al doping on the radiation responses of their silica-based host matrix and on the transitions between the energy states of rare-earth ions.
