Paper Abstract

A remarkable self-sustained thermo-optomechanical oscillator has been observed in various optical micro-cavities, which caused by competition among the thermal expansion, the thermo-optic effect, and Kerr effects as we scan the probing laser across a cavity resonance at various tuning rates. Oscillation periods in the thermo-optomechanical oscillator are considered to be related to the heat dissipate rate from the micro-cavity resonator bulk to the environment, and it is possible that the thermo dissipate rate can be measured by detecting oscillation periods. Although a nonlinear relationship between the heat dissipate rate and oscillation periods is exhibited, an artificial neural network is applied to identify the heat dissipate rate. Numerical results demonstrate that the method can be used to measure the heat dissipate rate effectively in the thermo-optomechanical oscillator based on a CaF2 whispering-gallery-mode resonator.
