Abstract

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 resonator's mechanical radial contour modes of frequency up to 1.35 GHz with high mechanical Q factor around 4,000 in air.

摘要

我们展示了用于在环境空气中进行共振操作的轮形硅光机械谐振器。光学回音壁模式的高精细度（加载光学品质因数高于500,000）使得轮形谐振器的频率高达1.35 GHz的机械径向轮廓模式能够在空气中以约4,000的高机械品质因数进行高效转换。
