AI中文摘要：
我们研究一种由具有相反面外磁化的成对层构成的磁光子晶体。尽管总磁化为零，这种反铁磁模式仍能打开光子带隙，产生非平凡拓扑相，并在带隙内频率下实现强交叉偏振光反射，可用于磁可调偏振旋转镜。我们系统探究该结构的光学性质，强调其与拓扑光子学、轴子电动力学的丰富联系。
英文摘要：
We investigate a magnetophotonic crystal formed by the pairs of layers with the opposite out-of-plane magnetization. Despite vanishing total magnetization such antiferromagnetic pattern opens photonic bandgap, gives rise to nontrivial topological phases and enables strong cross-polarized light reflection at frequencies inside the gap which can be harnessed for magnetically tunable polarization-rotating mirrors. We systematically explore optical properties of this structure highlighting fruitful connections to topological photonics and axion electrodynamics.
