从极化子弱局域化的角度，提出了相位共轭光波产生的微观机理。相位共轭波是探针光的时间反转传播，在杂质处极化子的弹性多次散射和时间反转过程之间的干涉作用下，相位共轭波得到增强。这是系统时间反转不变性的特征。我们列出了由于极化子的弱局域化而产生相位共轭波的几个特征。这些观察结果将用于检验目前的理论。
The microscopic mechanism of generation of phase-conjugated light waves is presented in terms of weak localization of polaritons. Phase-conjugated waves, which are the time-reversal propagation of probe light, are shown to be enhanced by constructive interference between elastic multiple scattering of polaritons at impurities and time-reversed processes. This is characteristic of the time-reversal invariance of the system. We list several characteristics of generation of phase-conjugated waves due to the weak localization of polaritons. These observations will be applied to check the present theory.
