We have developed a novel but simple approach to obtain ZnO microcombs with parallelogram stems and elongated hexagonal branches. We found that the present elongated hexagonal microcavity exhibited quite different features for its optical resonant modes due to the broken hexagonal symmetry. The resonant mode evolution of such microcavity was investigated systemically by using a spatially resolved spectroscopic technique. Theoretical analyses based on the plane wave mode and FEM simulations agreed well with the experimental results. We believe that our research allows us to have a deeper understanding of the controllable growth of novel optical cavities and the shape-dependent optical resonant modes.
我们已经开发出一种新颖但简单的方法来制备具有平行四边形茎和细长六边形分支的氧化锌微梳。我们发现,由于六边形对称性的破坏,目前这种细长的六边形微腔在其光学共振模式方面表现出截然不同的特征。通过使用空间分辨光谱技术,对这种微腔的共振模式演化进行了系统研究。基于平面波模式的理论分析和有限元模拟与实验结果吻合得很好。我们相信,我们的研究使我们能够更深入地理解新型光学腔的可控生长以及形状依赖的光学共振模式。
