Cavity optomagnonics has received considerable research interest in recent years, due to the coherent magnetic Brillioun light scattering in the ferromagnetic material. Here, we theoretically propose and numerically verify a feasible scheme for the full polarization tomography on photon statistics in an optomagnonic whispering-gallery-mode microresonator system in the weak-coupling regime. By performing the polarization pre- and post-selections to manipulate the polarization states of the input and output photons, we find that the rich sub- and super-Poissonian photon statistics can be selectively generated, thanks to quantum interferences. In the parameter space of phase delay, the evolution from photon bunching to antibunching indicates the change from phase to amplitude squeezing. Our obtained result has potential applications in tunable quantum polarized light sources based on the cavity optomagnonic platform in micro-nano scale. It also offers a deeper understanding for full quantum cavity optomagnonics.
近年来，由于铁磁材料中的相干磁布里渊光散射，腔光磁学受到了广泛的研究关注。在此，我们从理论上提出并通过数值验证了一种在弱耦合 regime 的光磁回音壁模式微谐振器系统中对光子统计进行全极化层析成像的可行方案。通过进行极化预选择和后选择来操纵输入和输出光子的极化状态，我们发现由于量子干涉，可以选择性地产生丰富的亚泊松和超泊松光子统计。在相位延迟的参数空间中，从光子聚束到反聚束的演化表明从相位压缩到幅度压缩的变化。我们得到的结果在基于微纳尺度腔光磁平台的可调谐量子偏振光源中具有潜在应用。它还为全量子腔光磁学提供了更深入的理解。
