Erbium concentration control and optimization in erbium yttrium chloride silicate single crystal nanowires as a high gain material
Increasing erbium concentration while minimizing the reduction of photoluminescence is an
important task for achieving erbium-based high-gain materials for integrated photonics
applications. Here, we demonstrate a strategy of controlled variation of Erbium density in the
growth of erbium yttrium chloride silicate (EYCS)((Er x Y 1− x) 3 (SiO 4) 2 Cl)) single crystal
nanowires by systematically varying x between 0 and 1. We show that, as a trade-off
between high Er density and suppressed upconversion, Er composition x= 0.3 provides the …
