Abstract: The optically mediated oscillation transfer between coupled cantilevers in the optomechanical system based on two-coupled-cantilever is realized. The intrinsic frequency of one of the cantilevers is tuned by optical trapping. A tunable two-mode optomechanical system is constructed. A parametric driving field is applied through periodically modulating the trapping power in order to parametrically couple the two cantilevers, which enables further experimental demonstration of coherent oscillation transfer between the cantilevers. The method is helpful to construct coherent phonon devices based on coupled micromechanical oscillator arrays.
