Functional imaging probes can help surgeons to accurately locate residual tumors for a complete destruction of malignant tissues with minimal damage to healthy ones that can lead to better patient survival and recovery. In our previous work, we demonstrated that the combination of spatial and temporal processing could yield image frames with a fast update rate and good image quality for superior tumor...
We demonstrate a micron-sized ultrahigh-Q (Qo=740,000) disk cavity by embedding it in a sunflower-type circular photonic crystal. The disk's fundamental mechanical radial-contour mode is optically transduced at 2.19 GHz with a displacement sensitivity of 6.4 am/Hz1/2.
