Abstract: 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) andWehrl 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.
