11. Vers une connaissance microscopique de la structure de verres de phosphate P2O5Layla Martin-Samos, Nikita S. Shcheblanov, Luigi Giacomazzi, Nicolas Richard, Nadege Ollier, 2020, popular article Abstract: Les propriétés d’amplification de la lumière des ions terres rares permettent en les incluant comme dopants dans le cœur des fibres optiques d’obtenir des sources laser et des amplificateurs de lumière compacts. Pour réduire la tendance à l’agrégation des terres rares qui diminuent leurs propriétés amplificatrices, le phosphore est employé comme co-dopant dans ces fibres. Cet article montre comment les méthodes de simulation à l’échelle atomique
peuvent aider a' l'optimisation de ce co-dopage en contribuant a' une meilleure comprehension de la structure des verres phosphates
[1] et des défauts qui leur sont liés [2]. Au CEA-DAM, ces resultats serviront aussi dans le cadre d'etudes sur le developpement de fibres optiques pour des mesures de dosimetrie radiative.
