从理论上提出了一种利用变形光学元件实现无源光腔中光波捕获的人工磁场的方法。特别是，当实现均匀磁场时，获得横向谐振器模式频谱的高度简并朗道能级结构，对应于光腔场的回旋运动。这可以通过无源光学谐振器的瞬态激励来探测。
A method to realize artificial magnetic fields for light waves trapped in passive optical cavities with anamorphic optical elements is theoretically proposed. In particular, when a homogeneous magnetic field is realized, a highly degenerate Landau-level structure for the frequency spectrum of the transverse resonator modes is obtained, corresponding to a cyclotron motion of the optical-cavity field. This can be probed by transient excitation of the passive optical resonator.
