We analyze the interplay between the spontaneous generated coherence and the squeezed field on the susceptibility of the atomic system. We find that by varying the intensity of the squeezed field the group velocity of a weak pulse can change from subluminal to superluminal. In addition we exploit the fact that the properties of the atomic medium can be dramatically modified by controlling the relative phase between the driving field and the squeezed field, allowing us to manipulate the group velocity at which light propagates. The physical origin of this phenomenon corresponds to a transfer of the atomic coherence from electromagnetically induced transparency to electromagnetically induced absorption. Besides, this phenomenon is achieved under nearly transparency conditions and with negligible distortion of the propagation pulse.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.71.063805http://journals.aps.org/open access535Level atomAnomalous-dispersionPropagationSystemInversionFieldGainTransparencyTransitionsRefractionÓptica (Física)2209.19 Óptica Física
