GHz optomechanical resonators with high mechanical Q factor in air


الملخص بالإنكليزية

We demonstrate wheel-shaped silicon optomechanical resonators for resonant operation in ambient air. The high finesse of optical whispering gallery modes (loaded optical Q factor above 500,000) allows for efficient transduction of the wheel resonators mechanical radial contour modes of frequency up to 1.35 GHz with high mechanical Q factor around 4,000 in air.
