Nonclassical effects are investigated in a system formed by two quantum wells, each of which is inside an open cavity. The cavities are spatially separated, linked by a fiber, and filled with a linear optical medium. Based on Husimi distributions (HDs) and Wehrl entropy, we explore the effects of the physical parameters on the generation and the robustness of the mixedness and HD information in the phase space. The generated quantum coherence and the HD information depend crucially on the cavity-exciton and fiber cavity couplings as well as on the optical medium density. The HD information and purity are lost due to the dissipation. This loss may be inhibited by increasing the optical susceptibility as well as the couplings of the exciton-cavity and the fiber-cavity. These parameters control the regularity, amplitudes, and frequencies of the generated mixedness.
在由两个量子阱组成的系统中研究非经典效应，每个量子阱都位于一个开放腔体内。这些腔体在空间上是分开的，通过光纤连接，并填充有线性光学介质。基于胡西米分布（HDs）和韦尔熵，我们探讨了物理参数对相空间中混合性和HD信息的产生及鲁棒性的影响。所产生的量子相干性和HD信息关键取决于腔 - 激子和光纤腔耦合以及光学介质密度。由于耗散，HD信息和纯度会丢失。这种损失可以通过增加光学敏感性以及激子 - 腔和光纤 - 腔的耦合来抑制。这些参数控制着所产生混合性的规律性、幅度和频率。
