Influence of Squeezed Vacuum on Bistable Behavior

The influence of squeezed vacuum input on the optical bistable behavior of a system of N three-level atoms which are simultaneously coupled to a coherent pump field and a squeezed vacuum input is investigated. It is shown that the squeezed vacuum will significantly increase the range of the optical bistability and this effect is phase-sensitive. The results exhibit that the optical bistability can be controlled by the squeezed vacuum input.
