Abstract: In this Letter, we report an approach to experimentally determine the optomechanical coupling coefficient of coupled cavities, taking advantage of the ultra-fine cavity positioning capability of a nanoelectromechanical system (NEMS) actuator design. The approach is simple and flexible and can measure the optomechanical coupling coefficient as a function of the coupled cavities' slot gap. In addition, the ratio of mechanical detunings of the odd and even resonance modes can make the existing approach to the decoupling of thermo-optic and optomechanical effects more precise and applicable to more types of cavities. © 2013 American Institute of Physics.
