The problem of the propagation of linearly polarized light in an optically anisotropic medium with spatially modulated gyrotropy is considered. The analysis has been carried out using optical Bloch equations in the approximation of a rotating wave. For clarity, the results are interpreted on the Poincaré sphere. It is demonstrated that under the resonance conditions, i.e., when the spatial frequency of modulation of gyrotropy coincides with the spatial frequency of polarization beats, a resonant increase in the amplitude of these beats is observed.

各向异性的各向异性介质中的空间共振

考虑了线性偏振光在具有空间调制的旋转性的光学各向异性介质中的传播问题。使用光学Bloch方程对旋转波进行了近似分析。为了清楚起见，在庞加莱球上解释了结果。已经证明，在共振条件下，即，当回旋调制的空间频率与极化节拍的空间频率一致时，观察到这些节拍的振幅共振增加。
