摘要: 在基于两个耦合悬臂梁的光力系统中通过光学调控的方法实现了振动在悬臂梁间的传递。利用光学囚禁作用调谐其中一个悬臂梁的本征频率,构造了一个可调谐两模光力系统。通过周期性调节囚禁光功率对系统施加一个参量驱动场,实现了悬臂梁间的参量耦合,并进一步在实验上完成了振动在悬臂梁间的相干传递。该方法有助于构造基于耦合微机械振子阵列的相干声子器件。

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.
