Phonon mediated electromagnetically induced absorption in cavity
optomechanics
   [PDF]

Kenan Qu, G. S. Agarwal
We predict the existence of the electromagnetically induced absorption (EIA) in the double cavity configurations of the optomechanical systems (OMS). We discuss the origin of the EIA in OMS which exhibit the existence of an absorption peak within the transparency window. We provide analytical results for the width and the height of the EIA peak. The combination of the EIT and EIA is especially useful for photon switching applications. The EIA that we discuss is different from the one originally discovered by Lezama et al in atomic systems and can be understood in terms of the dynamics of three coupled oscillators (rather than two) under different conditions on the relaxation parameters.
