Engineered properties in ceramized optical fibres
Résumé
DNP are observed in fibres when alkaline-earth elements (Mg, Ca and Sr) are incorporated. Mean size of the DNP, deduced from SEM pictures, depends on the composition... This last composition leads to a low loss fibre... From EDX measurements, we have observed that alkaline-earth elements and erbium ions are located inside or very close to the DNP. Fibre samples were spectroscopically analysed at room temperature. It was observed that erbium emission broadens in the DNP-doped fibres...
