Abstract

We investigate the light propagation in the Bose–Einstein condensate (BEC)-cavity system, where the collective density excitation of the BEC serves as a mechanical oscillator coupled to the optical cavity field. The existence of optomechanically-induced absorption (OMIA) is demonstrated theoretically in the cavity optomechanics system under two-photon detuning driven by two-tone fields. We give the physical origin of the OMIA and its manipulation by adjusting the power of the pump field in the system. Moreover, there will be a transition between the absorption dip and transmission peak via dominating the pump power. The OMIA in this strong coupled BEC-cavity optomechanics system will provide a platform for potential applications in photoswitching.
