All-Optical Switching between Optical Bistability and Multistability via Exciton Spin Relaxation

Asadpour, Seyyed, Hossein Hossein +3 more

光 bistability (OB ) 和在 4.8 nm ZnSe 单个量的井的光 multistability (OM ) 的所有光的协调控制基于激子和 biexciton 转变被调查。由使用一双锁阶段的激光脉搏，所有光的协调控制能被获得。有矩阵和麦克斯韦方程然后产出的密度的理论分析光 bistability 和光 multistability。由控制协调、支离破碎的过程， OB 和 OM 的紧张阀值能被修改，这被显示出。另外，在 OB 和 OM 之间或反过来也如此切换能为一些可控制的参数被发生，这被发现。光 bistability (OB ) 和在 4.8 nm ZnSe 单个量的井的光 multistability (OM ) 的所有光的协调控制基于激子和 biexciton 转变被调查。由使用一双锁阶段的激光脉搏，所有光的协调控制能被获得。有矩阵和麦克斯韦方程然后产出的密度的理论分析光 bistability 和光 multistability。由控制协调、支离破碎的过程， OB 和 OM 的紧张阀值能被修改，这被显示出。另外，在 OB 和 OM 之间或反过来也如此切换能为一些可控制的参数被发生，这被发现。

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.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.

Controlling the onset of OB/OM in a semiconductor quantum well system in an inverted Y-type configuration

Ali Raheli, Hamid Reza Hamedi, Mostafa Sahrai

Abstract The problem of optical bistability (OB) and optical multistability (OM) is numerically investigated in a four-level inverted Y-type semiconductor quantum well (SQW) structure immersed in a unidirectional ring cavity. In the four-level SQW system under consideration, a closed loop configuration is coupled to the upper level through a tunable probe field. We show that the OB threshold intensity can be controlled via the intensity of coupling fields which gives rise to the absorption variation of the probe field. In addition, due to the existence of the closed-loop configuration, the OB and OM behaviors of the proposed SQW medium are dependent on the relative phase of the applied fields. It is found that the OB can be switched to OM or vice versa by properly adjusting the relative phase of the applied fields. The results may provide new possibilities in real experiments for realizing an all-optical switching or coding element in a solid-state platform.Abstract The problem of optical bistability (OB) and optical multistability (OM) is numerically investigated in a four-level inverted Y-type semiconductor quantum well (SQW) structure immersed in a unidirectional ring cavity.
