提出了一种用于地震勘探加速度检测的硅基应力耦合光学跑道谐振器。加速度作用在质量块上，在一个轨道周期内会引起光学相位的变化，从而引起共振波长的偏移。通过系统地优化谐振腔结构和机械特性，数值模拟证明了在1 g加速度下52 pm的非常大的波长漂移。输入信号的最高频率可达200 Hz。这种硅基紧凑型高性能跑道谐振器在地震勘探中具有很大的潜力。
A silicon-based stress-coupled optical racetrack resonator with a crossbeam mass is proposed to detect acceleration for seismic prospecting. Acceleration applied on the crossbeam mass can result in optical phase changes in one racetrack cycle, which leads to a resonant wavelength shift. By systematically optimizing the resonator structure and mechanical characteristics, a very large wavelength shift of 52 pm under 1 g acceleration is demonstrated by numerical simulation. The maximum frequency of input signal can be up to 200 Hz. This silicon-based compact and high-performance racetrack resonator can have great potential for seismic prospecting.
