dc.description.abstractOptical microcavities have emerged as powerful tools for detecting single molecules and nanoparticles due to their exceptional sensitivity and label-free operation. However, the performance of ultra-high-Q microcavities is highly sensitive to factors such as ambient temperature fluctuations, mechanical vibrations, and laser frequency drifts, all of which destabilizing laser-cavity detuning and intracavity power. Optomechanical oscillation (OMO), a phenomenon driven by radiation pressure within the cavity, offers significant advantages for liquid-based sensing, but requires stringent conditions stable laser-cavity detuning for sustainable regenerative operation. In this thesis, we demonstrate stable, long-term OMO in an aqueous environment by implementing a Proportional-Integral (PI) locking
