We study the transmission and the reflection of light beams carrying orbital angular momentum through a dielectric multilayer structure containing phase-conjugating interfaces. We show analytically and demonstrate numerically that the phase conjugation at the interfaces results in a characteristic angular and radial pattern of the reflected beam, a fact that can be exploited for the detection and the characterization of phase conjugation in composite optical materials.
我们研究了携带轨道角动量的光束通过包含相位共轭界面的介质多层结构的传输和反射。我们通过解析和数值方法表明，界面处的相位共轭会导致反射光束呈现出特征性的角度和径向图案，这一事实可用于检测和表征复合光学材料中的相位共轭。
