Schematic diagram of the optomechanical system studied in the present paper. A strong coupling field of frequency ω c and a weak probe field of frequency ω p are injected into the cavity through the fixed partially transmitting left mirror. The right moving cavity mirror (denoted by x 1) and the second oscillator (denoted by x 2) coherently couple with each other. Only the moving cavity mirror interacts with the cavity field.
