报告摘要：

Microtubular cavities, which are self-assembled from prestrained nanomembranes, can support whispering-gallery mode (WGM) resonances. Owing to the subwavelength-thin cavity wall, optical evanescent field greatly extend out of cavity surfaces, allowing for efficient light-matter interactions. By coating plasmonic nanosturctures onto the microcavity surfaces, photon-plasmon coupling are studied relying on the interaction of WGM resonant light and localized surface plasmons. Owing to the ultra-high sensitivity to surface perturbations, the microtube cavities are able to detect surface dynamic process of molecule growth and desorption. In addition, novel types of photonic molecules based on microtube cavities are designed for the study of resonant mode hybridization. Moreover, we have demonstrated the generation of optical Berry phase in microtubular ring cavities. As a novel platform, microtubular cavities imply promising applications for enhanced light-matter interactions, optical tuning, photonic integration and quantum optics.
