在过去10年伴随着高品质回音壁模式微谐振腔的发展，腔光机力学(cavity optomechanics)在量子力学应用、精密测量和传感方面取得重大突破。然而迄今为止几乎所有的回音壁微腔光机力学研究都集中在各向同性固体微腔中展开，只有少量工作涉及固/液复合微腔和晶体微腔。本项目注重于一种研究不多但有重要应用价值的高Q光微流微泡腔的光机力学效应研究。基于课题组在光微流微泡腔和液晶光学研究方面的优势，本项目将研究液体/固体复合微泡微腔的光场/机械场耦合效应；在此基础上构建向列相液晶填充石英玻璃微泡复合微腔，研究其机械振动模式与液晶性质（如各向异性声速、密度等）的关系，以及外场（电场、磁场和温度场）调控改变液晶状态（取向、向列相/液相）时光机耦合和机械振动模式的变化；并进行光微流微泡腔中纳米颗粒质量检测研究。研究结果将大大丰富对回音壁微腔光机力学效应的理解，为微腔光机力学的应用开拓新领域。

With the development of high Q whispering gallery optical resonators, cavity optomechanics becomes an important research field and has achieved important breakthrough in quantum mechanics application, precise measurement and sensing. Up to now, almost all investigations are carried out with isotropic solid microcavities, only a few works were reported on solid/liquid hybrid cavities and crystal cavities. Here we propose studies on the optomechanical properties of a rarely explored but very important kind of microcavities (high Q optofluidic micro-bubble resonators). Based on previous background of expertise on micro-bubble resonators and liquid crystal optics, we would like to investigate the optomechanical coupling properties of solid/liquid hybrid microcavities, prepare liquid crystal/silica hybrid micro-bubble whispering gallery mode resonators, investigate and manipulate optomechanical properties of the novel anisotropic hybrid cavities by magnetic field, electric field and temperature, we will also investigate precise detection of nanoparticles in the optofluidic device. Our study will largely enrich the understanding of optomechanical properties of whispering gallery mode optical resonators and find new application fields for cavity optomechanics.
