We study a combination of a four-level electromagnetically induced transparency and second-order nonlinearity, and show that the efficiency of frequency conversion can be profoundly enhanced in an erbium-doped glass.

A combination of a four-level electromagnetically induced transparency and second-order nonlinearity is shown to enhance profoundly the efficiency of frequency conversion in an Er-doped glass owing to the pump-pulse slowing down.

Electromagnetically induced transparency (EIT) is reported in a solid-state material doped with erbium ions. In this paper we introduce the spectroscopic investigations we have conducted in order to identify the adequate $\ensuremath{\Lambda}$-like three-level systems in ${\text{Er}}^{3+}:{\text{Y}}_{2}{\text{SiO}}_{5}$ crystal, relevant for the demonstration of EIT. These results pave the way for nonlinear and quantum optics applications based on EIT at the telecom wavelength around $1.5\text{ }\ensuremath{\mu}\text{m}$.
