二氧化硅微球中的回音壁模式由可调谐连续波激光通过光纤锥体激发。高扫频速度可以观察到振铃现象。微球中的热非线性可以增强这种现象。我们的测量结果与动力学方程的理论预测非常吻合。
Whispering gallery modes in silica microspheres are excited by a tunable continuous-wave laser through the fiber taper. Ringing phenomenon can be observed with high frequency sweeping speed. The thermal nonlinearity in the microsphere can enhance this phenomenon. Our measurement results agree very well with the theoretical predictions by the dynamic equation.
