Abstract

We have analytically investigated the optomechanically induced transparency (OMIT) in two coupled optomechanical systems. We report that, the presence of two optomechanical couplings and one mechanical coupling between the two resonators, leads to different quantum interference paths and, generates single, double and triple-OMIT windows in the probe absorption spectrum. In particular, we have shown how the OMIT windows are affected by the system parameters, how to control the widths of the OMIT windows and how to control the transitions between the different OMIT windows.
