摘要
We propose a novel technique of generating multiple optomechanically induced transparency （OMIT） of a weak probe field in hybrid optomechanical system. This system consists of a cigar-shaped Bose-Einstein condensate （BEC）, trapped inside each high finesse Fabry-P6rot cavity. In the resolved sideband regime, the analytic solutions of the absorption and the dispersion spectrum are given. The tunneling strength of the two resonators and the coupling parameters of the each BEC in combination with the cavity field have the appearance of three distinct OMIT windows in the absorption spectrum. Furthermore, whether there is BEC in each cavity is a key factor in the number of OMIT windows determination. The technique presented may have potential applications in quantum engineering and quantum information networks.
