“…Self-imaging also can be realized in nonhomogeneous media, such as gradientindex (GRIN) media [2,3]. It is possible to realize the self-imaging effect in a cold atomic medium with electromagnetically induced transparency (EIT) [4][5][6]. EIT has attracted much attention since the 1990s [7].…”

In this paper, a special gradient-index electromagnetically induced transparency medium is induced with a Gaussian control field, which can be realized in a four-level ⁸⁷Rb cold atomic cloud. Special directional self-imaging and imaging transforming properties are studied in this work. Simulated results show that a complex object can be imaged in the cold atoms, as the control field substituted with the elliptical Gaussian beam, then the self-imaging is directional, which has potental application in encryption.

“…It should be mentioned that, in Refs. [15][16][17][18], since the conditions for electromagnetically induced transparency (EIT) [19,20] are satisfied, the probe light transmitting in the cold atomic media is very slow. The deflection of the slow light in atomic media has been observed experimentally [21,22] and studied in theory [23] .…”

We present the moments formalism theory to study the deflection of the slow signal light in the cold atomic media, which is under the condition of the Gaussian control laser and electromagnetically induced transparency. Deflection, the interesting phenomenon on quantum coherence, is testified by analytic and numerical methods. Results show that, as the signal light propagating in the medium, there would be an observable deflection before the general diffraction. Influences of the coupling intensity on deflection phenomenon and the beam waist of the signal light in the medium are also investigated.
