Abstract: The dynamical behavior of  whispering-gallery cavity optomechanical system under the action of a controlling laser and a probe laser is investigated.The origin of electromagnetically induced transparency (EIT) -like dips is analyzed.The existence of the analog of EIT and electromagnetically induced absorption (EIA) in the output field at the probe frequency in this optomechanical system is demonstrated.The pump-probe response for the whispering-gallery mode (WGM) shares the features of the Λ system in atoms.What’s more,the switching between the EIT and EIA is dominated by the pump detune.The demonstration of EIT in this optomechanical system provides a theoretical basis for the quantum information processing.

Key words: whispering-gallery modes optomechanical cavity, optomechanically induced transparency, optomechanically induced absorption, quantum information
