Short Abstract: Mechanical resonators are one of the most fundamental and omnipresent physical systems at all scales. They play a substantial role in radio-signal processing and sensing. My thesis aim is to unravel some important aspects of coupling light to mechanical objects. In particular, I will discuss two experiments performed at room temperature focused on applying optomechanics to technological challenges. The first experiment is related to the ability of optomechanical systems to detect small forces applied to a mechanical resonator. The second experiment of this thesis describes a fundamental challenge of nanoscale physics that is the synchronization of two optomechanical cavities connected by a weak coupling.
