Abstract
Abstract We analytically investigate the optical response of an optomechanical system with two mechanical driven resonators which are mutually coupled via Coulomb coupling. We report an efficient scheme to control the optical response by appropriate adjustment of the phase and the intensity of mechanical driving fields. Interestingly, tuning the phase and intensity of the mechanical driving fields lead to the manipulation of the weak probe field which changes its behavior from excessive absorption to significant amplification. In addition, we also show that by applying the driving field to the left (right) mechanical resonator, one can generate the absorption and amplification at the sideband windows (opacity point). Furthermore, the enhanced absorption and amplification strongly depends on whether the phase of mechanical driving fields are in phase or out of phase.
