摘要

We study theoretically the features of the output field of a quadratically coupled optomechanical system assisted with three-level atoms.In this system,the atoms interact with the cavity field and are driven by a classical field,and the cavity is driven by a strong coupling field and a weak signal field.We find that there exists a multi-window transparency phenomenon.The width of the transparent windows can be adjusted by controlling the system parameters,including the number of the atoms,the powers of the lasers driving the atoms and driving the cavity,and the environment temperature.We also find that a tunable switch from fast light to slow light can be realized in this system.
