Optomechanically induced amplification and perfect transparency in double-cavity optomechanics

Abstract: We study the optomechanically induced amplification and perfect transparency in a double-cavity optomechanical system. We find if two control lasers with appropriate amplitudes and detunings are applied to drive the system, the phenomenon of optomechanically induced amplification for a probe laser can occur. In addition, perfect optomechanically induced transparency phenomenon, which is robust to mechanical dissipation, can be realized by the same type of drive. These results are very important for signal amplification, light storage, fast light and slow light in the quantum information processes.
