Quantifying and controlling the magnetic dipole contribution to 1.5 $\mu$m light emission in erbium-doped yttrium oxide

Dongfang Li, Mingming Jiang, Sébastien Cueff +3

We experimentally quantify the contribution of magnetic dipole (MD) transitions to the near-infrared light emission from trivalent erbium-doped yttrium oxide (Er${}^{3+}$:Y${}_2$O${}_3$)…
