Elliptically Polarized

In this paper, we propose a scheme for manipulating the behavior of optical bistability (OB) and optical multistability (OM) in an N-type four-level atomic system. In the scheme, quantum interference is optimized by the left-handed and the right-handed fields of an elliptically polarized field (EPF). The threshold and the hysteresis cycle shape of OB and OM can be controlled by modulating the intensity of the EPF. Especially, the transition from OB to OM or vice versa can also be easily realized by proper tuning the phase difference between the left-handed and right-handed polarized fields under the optimal intensity of the EPF.

In this paper, the bistable behaviors of weak probe light in a unidirectional ring cavity with a four-level atomic system are discussed. We find that in the presence of spontaneously generated coherence (SGC), the medium is completely phase dependent and the intensity threshold of optical bistability can be controlled. The effect of an incoherent pumping field on optical bistability in the presence and absence of SGC is also analyzed. Moreover, the group index behavior of weak probe light is investigated. We show that the intensity threshold of optical bistability can be controlled by light propagation switching from slow to fast by different parameters of the atomic medium.
