Giant non-linearities accompanying electromagnetically induced
transparency
Le-Man Kuang, Guang-Hong Chen, Yong-Shi Wu
abstract: We develop a fully quantum treatment of electromagnetically induced
transparency (EIT) in a vapor of three-level $\Lambda$-type atoms. Both the
probe and coupling lasers with arbitrary intensities are quantized, and treated
on the same footing. In addition to reproducing known results on ultraslow
pulse propagation at the lowest order in the ratio of their Rabi frequencies,
our treatment uncovers that the atomic medium with EIT exhibits giant Kerr as
well as higher order non-linearities. Enhancement of many orders of magnitude
is predicted for higher-order refractive-index coefficients.
