A surface-acoustic wave (SAW) creates its own high-Q ultrasmall-volume whispering-gallery mode (WGM), different from the usual bulk acoustic WGMs, in an optical dielectric WGM resonator. We show that it is possible to realize an externally controllable, efficient triply resonant optomechanical interaction between two optical WGMs and the SAW WGM and to use such an interaction in various sensor applications.
声表面波(SAW)在光学介电体 WGM 谐振器中产生其自身的高品质因数超小体积 whispering-gallery 模式(WGM),与通常的体声波 WGM 不同。我们表明,有可能实现两个光学 WGM 与 SAW WGM 之间的外部可控、高效的三重共振光机械相互作用,并在各种传感器应用中使用这种相互作用。
