Toggle switch from optical bistability to multistability via an elliptically polarized field

Abstract

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.

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.

Phase knob for switching steady-state behaviors from bistability to multistability via spontaneously generated coherence

Zhonghu Zhu, Ai-Xi Chen, Wen‐Xing Yang +1 more

We conducted a theoretical investigation of the optical steady-state behavior in N four-level Y-type atoms driven coherently by a probe laser and a single elliptically polarized field (EPF) by means of a unidirectional ring cavity. It was found that the optical bistability can be observed for a wide regime of frequency detuning of the probe field, intensity of the EPF, and the atomic cooperation parameter. Interestingly, in principle the optical steady-state behavior can be switched from optical bistability to multistability or vice versa by adjusting the phase difference between two components of the polarized electric field of the EPF if the perfect spontaneously generated coherence of atoms is included. Our results illustrate the potential to utilize EPF for all-optical switching in atomic systems through the phase control, as well as provide guidance in the design for possible experimental implementations.

Controlling optical bistability, multistability and all-optical switching through multi-photon excitation process

Suman Garain, Suman Mondal, Kalan Mal +2 more

Abstract We present a theoretical study on optical bistability (OB), optical multistability (OM) and tunable all-optical switching in a four-level cascade type atomic system. The density matrix formalism is used to find out the response of the probe laser field. We explore OB and OM under unidirectional optical ring cavity configuration. A comparison between the effects of electromagnetically induced transparency and electromagnetically induced absorption windows on OB is presented. The threshold of OB and the hysteresis width can be tuned effectively by adjusting the applied coherent fields. A transition from OB to OM and vice-versa can be easily achieved by tuning the field parameters and the atomic cooperation parameter. Dynamic control of the probe laser propagating through the medium has been investigated. We also demonstrate conversion of a continuous wave input probe field into output switched pulse. The ON/OFF time of the switched probe pulse can also be controlled by tuning the field parameters.

Controllable optical bistability and multistability in asymmetric quantum wells via Fano-type interference

Dong Sun, Hongjun Zhang, Hui Sun

Abstract We theoretically investigate the hybrid absorptive-dispersive optical bistability (OB) and optical multistability (OM) behaviors induced by Fano-type interference in a four-subband asymmetric semiconductor double quantum wells scheme driven by a degenerate probe field and a coherent coupling field. We show that the appearance or disappearance of OB can be controlled by modulating the strength of the Fano-type interference. We also present the threshold and hysteresis cycle of the OB can be controlled by adjusting the intensity of the coherent coupling field. Moreover, OB can be switched to OM by tuning the frequency detuning of the coherent coupling field or vice versa. This interesting scheme may provide guidance for technological applications in optoelectronics and solid-state quantum information science.

Optical bistability forming due to a Rydberg state

Hamid Reza Hamedi, Mostafa Sahrai, Habib Khoshsima +1 more

We consider the behavior of optical bistability (OB) and multistability (OM) in a four-level atomic system involving a Rydberg state illuminated by a probe field as well as control and switching laser beams of larger intensity. When the switching field is absent, no OB arises because of the effect of Rydberg electromagnetically induced transparency. However, by application of the switching field, the hysteresis cycle appears to give rise to optical bistability, thanks to Rydberg electromagnetically induced absorption. It is further demonstrated that one can efficiently modify the OB threshold via suitable choices of system-controlling parameters. Interestingly, it is observed that this model can produce an optical switching between OB and OM with potential applications in logic-gate devices for optical communication.

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.
