Optical bistability via quantum interference from monolayer WSe2

Abstract

We conducted a theoretical investigation of optical bistability based on the dipole-allowed transitions in a three-level ladder-type WSe 2 system. The system interacts with a laser beam through a unidirectional ring cavity. Our results demonstrate that efficient control of bistability can be achieved by tuning the laser frequency, decay rate, and cooperation parameters. We also discuss the influence of absorption and dispersion processes on the optical bistability behavior. The optical bistability exhibits absorptive and hybrid characteristics in small- and intermediate-output fields, respectively. This study can inform the strategic design of 2D materials for fast and low-threshold all-optical switches, leveraging their significant optical nonlinearities and exciton binding energies.

Controllable optical bistability in a four-subband semiconductor quantum well system

Jiahua Li

We study optical bistability (OB) behavior based on intersubband transitions in asymmetric double quantum wells (QWs) where tunneling-induced quantum inference can be observed. The system interacts with a probe-laser field and a control laser field by means of a unidirectional ring cavity. We show that OB can be controlled efficiently by tuning the coupling strength of the tunneling, the Fano-type interference, and the intensity of the control field. The influence of the frequency detuning of the probe and control fields on the electronic OB behavior is also discussed. This investigation can be used for the optimal design of semiconductor QW systems to achieve fast and low-threshold all-optical switches, which is much more practical than that in an atomic system because of its flexible design and the controllable interference strength.

TWO-COLOR COHERENT CONTROL OF OPTICAL BISTABILITY IN ASYMMETRIC SEMICONDUCTOR QUANTUM WELLS

Jiahua Li, Xiangying Hao

We investigate optical bistability in intersubband transitions of an asymmetric semiconductor quantum well structure that has equidistant transitions between three subbands of the system and is placed in a unidirectional cavity. The system is simultaneously coupled by a fundamental field and its second harmonic. The second harmonic field acts as a control field and significantly influences the optical bistability. In addition, the two-color coherent control of optical bistability by the relative phase of the fundamental and the second harmonic fields is shown. The influence of the electronic cooperation parameter on the OB behavior is also discussed. This investigation may be used for optimizing and controlling the optical switching process in the SQW solid-state system, which is much more practical than that in the atomic system because of its flexible design and the controllable interference strength.

Double-cavity optical bistability and all-optical switching in four-level N-type atomic system

Yu-Yuan Chen, Yanan Li, Ren-Gang Wan

We analyze the absorptive and hybrid absorptive–dispersive double-cavity optical bistability behavior in a four-level N-type atomic system driven by two optical fields circulating inside two independently unidirectional ring cavities and a trigger field outside the cavities. In this system, the two-photon absorption and cross Kerr nonlinearity play significant roles in the formation of bistability and can be controlled efficiently due to the quantum interference effect, and then the resulting nonlinear behavior exhibits different features from the two/three-level schemes. It is shown that the threshold values and hysteresis cycle width of the bistable curve can be manipulated via the adjustment of the system parameters. Meanwhile, we also obtain double-beam optical multistability. When adding positive and negative pulses to the cavity input, all-optical steady-state switching for the two cavity outputs can be achieved simultaneously. Therefore, the proposed scheme may have potential applications in all-optical communication and computing.

Effective control and switching of optical multistability in a three-level V-type atomic system

Abdelsalam H. M. Abdelaziz, Amarendra K. Sarma

We theoretically analyze the behavior of single optical bistability (OB), double OB, and tristability (OT) in a three-level V-type atomic system confined in a unidirectional optical ring cavity. The physics behind the emergence of various bistable and tristable states, and switching from the absorptive to the dispersive characteristics, are explored. The role of probe- and control-field detunings on the input-output characteristics is probed. Further, it is found that the switching between various bistable phenomena is defined by the ratio between the absolute peak values of the parameters describing dispersion and absorption, respectively. This ratio sets a criterion for obtaining absorptive OB, OT, double OB, and dispersive OB. The role of control-field intensity and detuning as well as the cooperation parameter on the input-output characteristics are explored. Finally, a scheme is discussed to control the width of the middle branch of double OB and OT as well as single OB.

The optical bistability (OB) in the quantum dot molecules with four energy levels in a unidirectional ring cavity has been investigated. The authors find that the OB behaviour in the proposed system can be controlled by the system's different parameters such as electronic cooperation parameter, Rabi frequency of the two coupling laser field, decay rate, three frequency detuning, in which the parameters sensitivity is studied. The proposed system can be used for all optical switching and logic.

Optical bistability via quantum interference in a four-level atomic medium

We theoretically investigate optical bistability (OB) behaviour in a four-level atomic system confined in a unidirectional ring cavity. It is shown that OB can be controlled by adjusting the intensity of the coupling field and the value of the cooperativity parameter. More importantly, our numerical results show that the threshold intensity of OB can be reduced without decreasing the range of the hysteresis loop via adjusting the effect of spontaneously generated coherence (SGC) or the relative phase between two applied fields. The influence of the frequency detuning of the coupling field on the OB behaviour is also discussed.
