Abstract
This paper provides a way of realizing light wave localization via electromagnetically induced transparency, which is quite different from the traditional, off-resonant mechanism-based Aubry-Andre model. The localization of light in a one-dimensional atomic medium is reported in this paper. The medium suggested in this paper is a resonant cold atomic ensemble with N-configuration, which can be modulated to be a quasi-periodic structure in the center area. As the paraxial signal field propagates in the medium, localization can be realized. The localization point and the propagation properties of the signal field are studied in this paper.
