The phenomenon of optical bistability is studied for the three-level atomic system in V-configuration confined in a unidirectional optical ring cavity, and the effects of quantum interference and coupling field are investigated. The possibility of obtaining optical multistability in the system by controlling quantum interference and coupling field strength is also discussed.

Abstract We have investigated the optical bistability and multistability behaviors in a three-level V-type system via both coherent and incoherent fields inside a unidirectional ring cavity. We find that the appearance and disappearance of optical bistability (OB)/optical multistability (OM) can easily be controlled by adjusting systemic parameters. Our scheme opens up a new possibility for realizing transition from OB to OM or vice versa for potential applications in information networks and processing with increased capacity.

A novel mechanism is proposed for optical bistability utilizing the population trapping which may occur in a coherent superposition of sublevels in a three-level system. The resulting bistability does not require atomic saturation and is insensitive to Doppler and laser bandwidth effects.
