Unlike many implementations in homogeneously broadened media, these systems exhibit inhomogeneous broadening of their optical and spin transitions typical of solid-state materials. We observe EIT lineshapes typical of atomic gases, including a crossover into the regime of Autler-Townes splitting, but with the substitution of the inhomogeneous widths for the homogeneous values. We obtain quantitative agreement between experiment and theory for the width of the transpa","authors_text":"Alan L. Migdall, Elizabeth A. Goldschmidt, Haoquan Fan, Kumel H. Kagalwala, Sergey V.
