Control of optical bistability via an elliptically polarized light in a four-level tripod atomic system
Duo Zhang, Jiahua Li, Chunling Ding +1 more
A scheme for optical bistability (OB) is proposed, in which the atom is in a four-level tripod configuration and driven by a single elliptically polarized light. It is demonstrated that the behaviors of OB can be controlled efficiently by adjusting the system parameters appropriately. Moreover, phase-controlled OB can be realized as well.
