Tunable double optomechanically induced transparency in a dual-species Bose–Einstein condensate

Abstract

A novel technique for generating double optomechanically induced transparency (OMIT) in a weak probe field in an optomechanical system is proposed. This system consists of a cigar-shaped dual-species Bose–Einstein condensate which is trapped inside a high-finesse Fabry–Perot cavity. Analytical solutions are given for the absorption and dispersion spectra. The interspecies interaction and the coupling strengths have, as a result, the appearance of two distinct OMIT windows in the absorption spectrum. Furthermore, the coupling strengths, interspecies and intraspecies interaction strengths are used to control the OMIT behavior. We give a certain set of experimental parameters for observing these phenomena in the laboratory. The technique presented may have potential applications in quantum engineering and quantum information networks.
