我们分析了光学非线性材料微腔中的二次谐波产生过程。我们表明，在腔厚度远小于材料相干长度且精度足够高的情况下，不需要相位匹配程序即可获得相当大的光学转换产率。因此，可以利用 III-V 族或 II-VI 族材料的大光学非线性磁化率，尽管这些化合物不是双折射的。结果表明，通过调整镜面反射率相位，可以获得泵浦波和谐波之间没有相位失配的双谐振腔。
We analyze the second‐harmonic generation process in a microcavity of optical nonlinear material. We show that, in the case when the cavity thickness is much smaller than the material coherence length and for sufficiently high finesses, no phase match procedures are necessary to obtain a quite large optical conversion yield. It is thus possible to capitalize on the large optical nonlinear susceptibilities of III‐V or II‐VI materials though these compounds are not birefringent. It is shown that by adjusting mirror reflectivity phases it is possible to obtain doubly resonant cavities in which there is no phase mismatch between pump and harmonic waves.
