We investigate the optical behavior of a single Laguerre–Gaussian cavity optomechanical system consisting of two mechanically rotating mirrors. We explore the effects of various physical parameters on the double optomechanically induced transparency (OMIT) of the system and provide a detailed explanation of the underlying physical mechanism. Here, we show that the momentum is not the cause of the current double-OMIT phenomena; rather, it results from the orbital angular momentum between the optical field and the rotating mirrors. Additionally, the double-OMIT is simply produced using a single Laguerre–Gaussian cavity optomechanical system rather than by integrating many subsystems or adding the atomic medium as in earlier studies. We also investigate the impact of fast and slow light in this system. Finally, we show that the switching between ultrafast and ultraslow light can be realized by adjusting the angular momentum, which is a new source of regulating fast-slow light.
