摘要

在窃窃私语通道模式谐振器中，当两个或多个模式具有相同的频率时，就会出现静态光场干涉图样。本文报道了微泡谐振腔中光学三次谐波（TH）模的干涉图样的产生。我们发现干涉图样的形成有两条路径，一是两个简并基模产生两个TH模，基模和TH模都形成干涉图样。而在另一种路径中，除了直接THG过程产生THG模式外，只有一种基本模式，即光-机械耦合辅助THG过程产生二次THG模式。因此，只有TH模形成干涉图样。我们的工作将窃窃廊模式干涉图样的观察扩展到非线性光场。

Interference pattern generation of optical third harmonic whispering gallery modes in microbubble resonators

Static optical field interference pattern in whispering gallery mode resonators occurs when two or more modes have the same frequency. Here we report interference pattern generation of the optical third harmonic (TH) modes in microbubble resonators. We found that the interference patterns form via two paths, one is two degenerate fundamental modes generate two TH modes, both fundamental modes and TH modes form interference patterns. Meanwhile in the other path, only one fundamental mode is involved, in addition to the direct THG process that generates a TH mode, a secondary TH mode comes from opto-mechanical coupling assisted THG process. Therefore only TH modes form interference pattern. Our work extends the observation of interference pattern of whispering gallery modes to nonlinear optical fields.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
