Dans les fibres optiques à base de silice dopée erbium (Er3+), le phosphore se place de manière préférentielle autour des ions de terre rare pour former un environnement très ordonné localement. Cependant, cet arrangement décrit dans la littérature n'a jamais donné de signature spectroscopique. Dans cette communication nous présentons les...

In rare-earth-doped silica optical fibres, the homogeneous distribution of amplifying ions and part of their spectroscopic properties are usually improved by adding selected elements, such as phosphorus or aluminum, as structural modifier. In erbium ion (Er3+) doped fibres, phosphorus preferentially coordinates to Er3+ ions to form regular...

A new route was recently proposed to modify some spectroscopic properties of rare-earth ions in silica-based fibers. We had shown the incorporation of erbium ions in amorphous dielectric nanoparticles, grown in fiber preforms. Here we present the achieved stabilization of nanometric erbium-doped dielectric nanoparticles within the core of...
