Abstract

We investigate the optical bistability (OB) in a duplicated two-level system contained in a ring cavity.The atoms are driven by two orthogonally polarized fields with a relative phase.The OB behavior of such a system can be controlled by the amplitude and the relative phase of the coupling field, and it is possible to switch between bistability and multistability by adjusting the relative phase.

Controllable optical bistability and multistability in a double two-level atomic system

Jing Wu, Xin‐You Lü, Lili Zheng

We theoretically investigate the behaviour of optical bistability (OB) and optical multistability (OM) in a generic double two-level atomic system driven by two orthogonally polarized fields (a π-polarized control field and a σ-polarized probe field). It is found that the behaviour of OB can be controlled by adjusting the intensity or the frequency detuning of the control field. Interestingly enough, our numerical results also show that it is easy to realize the transition from OB to OM or vice versa by adjusting the relative phase between the control and probe fields. This investigation can be used for the development of new types of devices for realizing an all-optic switching process.

CONTROLLING THE OPTICAL BISTABILITY AND MULTISTABILITY VIA ATOM LOCALIZATION

Marziye Moghannian, Azar Vafafard, Mohammad Mahmoudi

We investigate optical bistability (OB) and optical multistability (OM) behaviors in a triply driven five-level atomic system.It is shown that the system has bistable behavior and can be controlled by intensity of applied fields.We find that OB switches to OM via interference induced among the Rabi-split resonance.We consider a superposed one-dimension standing wave, generated by two optical fields, and it is demonstrated that the OB and OM behaviors depend on the position of localized atoms as well as the relative phase of applied fields.

Phase control of optical bistability and multistability in a tripod four-level atomic medium

Xionghui Hu, Hongjun Zhang, Hui Sun +3 more

Optical bistability and multistability behaviors are investigated in a tripod four-level atomic configuration, including a unidirectional ring cavity. We find that optical bistability and multistability can be obtained by changing the relative phase of the driven fields and the intensity of the microwave field. In addition, we can switch optical bistability to optical multistability by adjusting the relative phase of the driven fields or vice versa, and the threshold can be controlled via changing the parameters of the scheme.

Controllable Optical Bistability and Multistability in a Four-Level Atomic System with Closed-Loop Configuration

Xin‐You Lü, Jiahua Li, Ji-Bing Liu

We theoretically investigate optical bistability (OB) and multistability (OM) behaviour of a closed-loop configuration atomic system driven by a degenerate coupling field and a degenerate probe field inside a unidirectional ring cavity. It is found that the OB and OM behaviour can be controlled by adjusting the intensity and the frequency detuning of the coupling field, respectively. Interestingly, our numerical results show that it is easy to realize the transition from OB to OM or vice versa by adjusting the intensity of the coupling field under a appropriate frequency detuning. The effect of the atomic cooperation parameter on the OB behaviour is also discussed.

Phase and amplitude control of optical bistability in quantum dot molecules

We investigate the optical bistability (OB) behavior in a unidirectional ring cavity containing an asymmetric semiconductor double quantum dot (QD) system that forms a three-level V type system. We apply a probe and a coupling field to the system and it is shown that in the presence of inter-dot tunneling, the bistability of the system can be controlled by amplitude and relative phase of applied fields.

Controlling Optical Bistability and Multistability in a Three-level ∧-type Atomic System Under the Nonresonant Condition

Zhiping Wang

Under nonresonant condition,we theoretically investigate the optical bistability(OB) and multistability(OM) behaviors in a three-level ∧-type system using a microwave field driving a hyperfine transition between two lower states inside the unidirectional ring cavity.The results show that the optical bistability behavior can be controlled by adjusting the intensity and the frequency detuning of the coupling field,respectively.It is also found that the microwave field plays an important role in achieving the multistability.The influence of the atomic cooperation parameter on the OM behavior is discussed at last.
