We propose a hybrid optomechanical system that includes a two-level atom and a single Laguerre–Gaussian (L–G) optomechanical cavity with two rovibrational mirrors, where optomechanical coupling originates from the exchange of momentum and angular momentum between the L–G light and the mirrors. Based on this platform, we theoretically studied the optical response of the probe field, including multiple optomechanically induced transparency, Fano resonance, and group delay. The results indicate that by selecting appropriate parameters, five transparent windows and fast/slow light can be achieved. Our study can promote the development of quantum communication technology and optical devices.
