Double transparency with slow and fast light in an optomechanical system

Abstract We propose a system to generate optomechanically induced transparency (OMIT) by considering two atoms in a cavity. The emission spectrum has been manipulated through dipole–dipole interaction between the two atoms enclosed in an optomechanical cavity (Mirza, 2016). We consider the same setup and investigated the characteristics of the output probe field. One mirror of the cavity is coherently driven through pump and probe optical fields whereas the other mirror of the cavity has a mechanical oscillator via radiation pressure. We report the interaction of two atoms with the optical cavity which exhibits the OMIT in the output probe field. Based on our theoretical results, we find that the OMIT of the probe field can be manipulated via optomechanical interaction ( g m c ), the interaction of atoms with a cavity ( g a c ) and the dipole–dipole interaction ( J ). Interestingly, we find double OMIT at two different frequencies in the presence of three parameters such as g m c , g a c and J . In addition, the medium exhibits slow and fast light at two different frequencies.
